Description

Technical Field

[0001] The utility model relates to the field of showers, in particular to a valve body connection structure and a shower. Background Art

[0002] A shower head is usually composed of a shower head, a valve body connection structure, an inlet and outlet water pipe and other parts, which can realize functions such as adjusting water temperature, flow rate, switching water channels and so on. The valve body connection structure usually includes components such as a temperature regulating valve, a water channel switching valve, a connecting pipe and a shell. The temperature regulating valve and the water channel switching valve are respectively fixed on the base of the shell, and the connecting pipe connects the temperature regulating valve and the water channel switching valve. In the prior art, the connecting pipe usually adopts a rigid connector such as a copper rod. Due to the change of the fixed position of the shell base and the valve body caused by the shell electroplating process, and the valve body connection is in a pressure-blocked state at the moment of valve opening and closing, the connection ends of the two valve bodies are offset axially or radially, and accordingly the connection between the connecting pipe and the valve body and the connection between the valve body and the shell base are under stress, which can easily cause the connection to deform or crack over time. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and to provide a valve body connection structure and a shower to avoid deformation or cracking due to stress at the connection between the connecting pipe and the valve body.

[0004] To achieve the above objectives, the present invention and its related embodiments adopt the following technical solutions but are not limited to the following solutions:

[0005] The first technical solution relates to a valve body connection structure, which is suitable for installation in a shower housing, and includes two valves and a flexible connecting pipe. The flexible connecting pipe is suitable for bending, and the two ends of the flexible connecting pipe are respectively connected to the water outlet end of one of the valves and the water inlet end of the other valve; the flexible connecting pipe forms a plug-in fit with at least one of the valves, and one of the plug-in fitting valve and the flexible connecting pipe is provided with a plug-in channel, and the other is provided with a plug-in portion suitable for inserting into the plug-in channel.

[0006] The second technical solution is based on the first technical solution, wherein the plug-in portion is provided with at least one sealing structure along the insertion direction to seal with the plug-in channel.

[0007] The third technical solution is based on the first technical solution, and the valve body connection structure also includes a retaining spring, the plug-in channel is provided with a parallel channel passing through the outer wall, and the outer wall of the plug-in part is provided with an annular groove; the retaining spring is elastic, and the retaining spring is suitable for extending into the parallel channel and engaging with the annular groove, and has a gap with at least one groove wall of the annular groove.

[0008] The fourth technical solution is based on the third technical solution, wherein the outer wall of the plug-in portion is provided with a mounting portion, and the mounting portion is provided with an abutment surface, which is suitable for abutting and cooperating with the end face of the plug-in channel so that the parallel channel faces the annular groove.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the periphery of the mounting portion is a regular hexagon.

[0010] The sixth technical solution is based on the first technical solution, wherein the flexible connecting pipe is made of PERT material.

[0011] The seventh technical solution is based on the first technical solution, wherein the base of the shell is provided with a screw column, and the two valves are fixed on the screw column by screws.

[0012] The eighth technical solution relates to a shower, which includes a cold water inlet pipe, a hot water inlet pipe, at least one water outlet and a valve body connection structure described in any one of the first to seventh technical solutions, the two valves being a temperature regulating valve and a water channel switching valve, the temperature regulating valve being connected to the cold water inlet pipe and the hot water inlet pipe, and the water channel switching valve being connected to and suitable for switching the water outlet.

[0013] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0014] In the first technical solution, the valve body connection structure is installed in the shower housing and includes two valves and a flexible connecting pipe; the flexible connecting pipe is suitable for bending, and the two ends of the flexible connecting pipe are respectively connected to the water outlet end of one of the valves and the water inlet end of the other valve; the flexible connecting pipe forms a plug-in fit with at least one of the valves, and one of the plug-in fitting valves and the flexible connecting pipe is provided with a plug-in channel, and the other is provided with a plug-in portion suitable for inserting into the plug-in channel. Thus, when the water inlet end of one of the valves is axially offset relative to the water outlet end of the other valve due to a change in the connection position between the housing and the valve body caused by the electroplating process, or due to momentary pressure buildup when the valve is switched, the flexible connecting tube and the two valves interact axially. Since the flexible connecting tube forms a plug-in fit with at least one of the valves, one of the plug-in fit valve and the flexible connecting tube is provided with a plug-in channel, and the other is provided with a plug-in portion suitable for inserting into the plug-in channel, the flexible connecting tube and at least one of the valves can move relative to each other, thereby avoiding the influence of axial force on the connection between the flexible connecting tube and the valve body, and the influence of force transmission on the connection between the valve body and the housing. When the water inlet end of one of the valves is radially offset relative to the water outlet end of the other valve due to a change in the connection position between the housing and the valve body caused by the electroplating process, or due to momentary pressure buildup when the valve is switched, a torsional force is generated at the connection between the flexible connecting tube and the valve body. Since the flexible connecting tube is suitable for bending, it is subjected to the torsional force and is bent and deformed radially and relaxes, thereby avoiding the influence of torsional force on the connection between the flexible connecting tube and the valve body, and the influence of force transmission on the connection between the valve body and the housing. Compared with the existing technology, the flexible connecting tube eliminates the influence of torsional force by its bending property, and the plug-in matching structure of the plug-in part inserted into the plug-in channel eliminates the influence of axial force, thereby avoiding the connection between the flexible connecting tube and the valve body and the connection between the valve body and the shell from being subjected to force due to offset, resulting in deformation or cracking over time.

[0015] In the second technical solution, the sealing structure is used to prevent water leakage at the connection between the flexible connecting pipe and the valve.

[0016] In the third technical solution, the retaining spring is elastic and suitable for extending into the parallel channel and engaging with the annular groove, so that the flexible connecting tube is relatively fixed to the water inlet end or the water outlet end of at least one of the valves; and there is a gap between the retaining spring and at least one groove wall of the annular groove. When the flexible connecting tube is subjected to an axial force, due to the elasticity of the retaining spring, it deforms radially when the axial force is transmitted, thereby allowing the flexible connecting tube to move axially within a certain range relative to the water inlet end or the water outlet end to eliminate the axial force.

[0017] In the fourth technical solution, the abutting surface is abutted and matched with the end surface of the insertion channel so that the parallel channel faces the annular groove, which facilitates the positioning and installation of the retaining spring.

[0018] In the fifth technical solution, the periphery of the mounting portion is a regular hexagon so as to be assembled with a hexagonal sleeve, which is convenient for batch installation.

[0019] In the sixth technical solution, PERT material has good flexibility, a wide applicable temperature range, and low cost.

[0020] In the seventh technical solution, the structure of the base with screw columns is relatively simple, which is convenient for the integrated modular production of the shell.

[0021] In the eighth technical solution, the shower includes the valve body connection structure in the first to seventh technical solutions, and has corresponding effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Compared with the prior art, this embodiment has the following beneficial effects:

[0050] In this embodiment, the temperature regulating valve 2 and the water path switching valve 3 are respectively fixed to the screw column 11 of the base of the shell 1 with screws, and the two ends of the flexible connecting pipe 4 are respectively a first plug-in portion 42 and a screw-connecting portion 43. The water outlet end 23 of the temperature regulating valve 2 is provided with an internal thread 231 which is threadedly matched with the screw-connecting portion 43, and the water inlet end of the water path switching valve 3 is provided with a first plug-in channel 31 suitable for the first plug-in portion 42 to be inserted for plug-matching, and the flexible connecting pipe 4 is suitable for bending; therefore, when the connection position between the shell 1 and the valve body changes due to the electroplating process of the shell 1, or the valve is instantly pressurized when it is switched, and the water inlet end of the water path switching valve 3 is axially offset relative to the water outlet end 23 of the temperature regulating valve 2, the flexible connecting pipe 4 and the two valves interact with each other in the axial direction. The switching valve 3 forms a plug-in fit, and the first plug-in portion 42 is suitable for being inserted into the first plug-in channel 31, so that the flexible connecting tube 4 and the water switching valve 3 can move relative to each other, avoiding the influence of the axial force on the connection between the flexible connecting tube 4 and the valve body and the screw column 11; when the connection position between the shell 1 and the valve body changes due to the electroplating process of the shell 1, or due to the instantaneous pressure buildup when the valve is switched, the water inlet end of the water switching valve 3 is radially offset relative to the water outlet end 23 of the temperature regulating valve 2, and a torsional force is generated at the connection between the flexible connecting tube 4 and the valve body; since the flexible connecting tube 4 is suitable for bending, the flexible connecting tube 4 is subjected to the torsional force and is bent and deformed radially and becomes loose, thereby avoiding the influence of the torsional force on the connection between the flexible connecting tube 4 and the valve body and the screw column 11. Compared with the prior art, the flexible connecting tube 4 eliminates the influence of torsional force by its bending property, and the flexible connecting tube 4 and the water channel switching valve 3 form a plug-in fitting structure in which the first plug-in portion 42 and the first plug-in channel 31 cooperate to avoid the influence of axial force; thereby preventing the connection between the flexible connecting tube 4 and the valve body and the screw column 11 from deformation or cracking due to long-term force.

[0051] In this embodiment, the first plug-in portion 42 is provided with a first sealing groove 422 and the threaded portion 43 is provided with a second sealing groove 432 for respectively mounting sealing rings, thereby preventing water leakage at the connection between the flexible connecting pipe 4 and the water channel switching valve 3 and the temperature regulating valve 2.

[0052] In this embodiment, the retaining spring 5 is elastic and suitable for extending into the parallel channel 32 and engaging with the first annular groove 421, so that the flexible connecting tube 4 and the water inlet end of the waterway switching valve 3 are relatively fixed; and there is a gap between the retaining spring 5 and at least one side groove wall of the first annular groove 421. When the flexible connecting tube 4 is subjected to an axial force, due to the elasticity of the retaining spring 5, it deforms radially when the axial force is transmitted, thereby allowing the flexible connecting tube 4 to move axially relative to the water inlet end within a certain range to eliminate the axial force.

[0053] In this embodiment, the first abutting surface 424 abuts against the end surface of the first insertion channel 31 so that the parallel channel 32 faces the first annular groove 421 , which facilitates the positioning and installation of the clamping spring 5 .

[0054] In this embodiment, when the second abutting surface 434 and the end surface of the water outlet end 23 are abutted and matched, the threaded engagement is completed, which facilitates sensing that the flexible connecting pipe 4 and the temperature regulating valve 2 are screwed into place.

[0055] In this embodiment, the periphery of the first mounting portion 423 and the second mounting portion 433 is a regular hexagon, which is convenient for batch installation using a hexagonal socket.

[0056] In this embodiment, the PERT material has good flexibility, a wide applicable temperature range, and low cost.

[0057] In this embodiment, the structure of the screw column 11 provided on the base of the housing 1 is relatively simple, which facilitates the integrated modular production of the housing 1 .

[0058] Example 2

[0059] Compared with Example 1, Example 2 is different in that the flexible connecting tube 4 and the temperature regulating valve 2 are also plug-in matched, and a second plug-in channel is provided at the water outlet 23 of the temperature regulating valve 2, and the flexible connecting tube 4 is provided with a second plug-in portion, and the second plug-in portion is suitable for extending into the second plug-in channel; similar to Example 1, the second plug-in portion is successively composed of a third mounting portion, a second annular groove and a third sealing groove along the plug-in direction, and the third mounting portion has a third abutting surface suitable for abutting with the end face of the second plug-in channel, and the periphery of the third mounting portion is a regular hexagon to facilitate the installation of a hexagonal sleeve; the second plug-in channel is provided with a parallel channel 32, and the parallel channel 32 is suitable for the retaining spring 5 to extend into and abut against the second annular groove, so that the retaining spring 5 is clamped with the flexible connecting tube 4, and when the retaining spring 5 is clamped with the second annular groove, there is a gap between it and at least one side groove wall of the second annular groove, so that the flexible connecting tube 4 can move axially relative to the second plug-in channel within a certain range. Compared with the valve body connection structure of the first embodiment, the second embodiment has a plug-in matching structure in which both ends of the flexible connecting tube 4 are plug-in parts inserted into the plug-in channel. When there is an axial force, the flexible connecting tube 4 moves and adjusts relative to the temperature regulating valve 2 and / or the water channel switching valve 3 along the plug-in channel, which is more flexible.
