Description

Technical Field

[0001] The utility model relates to the technical field of bathroom showers, in particular to an installation structure of a control valve on a shower rod. Background Art

[0002] In the prior art, some shower rods are provided with a body, an inner core tube disposed in the body, and a top spray shower and a side spray nozzle connected to the inner core tube. The top spray shower can discharge water downward, and the water discharged from the side spray nozzle can be used to shower the user's waist or back, thereby making the shower rod more functional. In order to facilitate the water discharge control of the top spray shower and the side spray nozzle, a water flow control valve is usually provided on the shower rod. Existing water flow control valves generally include a valve core, a valve stem, and a drive switch. The valve core and the valve stem are both non-detachable integrated structures. When the shower rod is assembled, the valve core and the valve stem need to be installed as a whole. In this way, the installation of the control valve requires the cooperation of the body of the shower rod to fix the control valve.

[0003] During production, in order to ensure that the sealing performance of the inner core tube meets the product requirements, the inner core tube needs to be tested for water tightness before leaving the factory. During the test, the control valve needs to be installed on the inner core tube to form a sealed connection with the water path of the inner core tube. At this time, as mentioned above, the main body needs to be assembled together to fix the control valve. That is to say, in the prior art, when the inner core tube with the control valve installed is tested for sealing, the main body needs to be tested together, and the main body is an appearance component. It is inevitable that bumps will occur during the test, resulting in a poor appearance and a waste of production costs. Utility Model Content

In this way, the inner core tube with the valve core installed can be directly used for water sealing test independently, without using the main body as the installation matching part of the control valve, so that the water sealing test does not need to be carried out with the main body, thereby effectively avoiding the problem of damage to the appearance of the main body during the test, and the structure is simple and reliable. In addition, since the inner core tube needs to withstand water pressure, a material with good strength can be selected, and the main body of the utility model does not need to be used to withstand water pressure, so the material requirements are not high, and the range of optional materials is wider. In the prior art, since the main body needs to limit the control valve, the main body needs to withstand the water pressure transmitted by the control valve, so the strength requirements of the main body are generally large, otherwise the main body is easily deformed outwards due to water pressure, resulting in poor appearance, and even interference with the control of the valve action.

[0041] Please refer to Figures 1 to 9 A preferred embodiment of the utility model provides a mounting structure for a control valve on a shower rod, comprising:

[0042] The body 10 is a hollow structure, and a through hole 11 is provided on the side wall of the body 10;

[0043] The inner core tube 20 is sleeved in the body 10;

[0044] The control valve 30 includes a valve core 31 and a valve stem 32 which are separately arranged, and a drive switch 33 connected to the valve stem 32, wherein the valve core 31 can be movably and sealedly installed in the inner core tube 20 to cut off or switch the water flow in the inner core tube 20, the water path of the valve core 31 is sealed and connected to the water path of the inner core tube 20, the inner end of the valve stem 32 is linked with the valve core 31 through the through hole 11, and the outer end of the valve stem 32 is connected to the drive switch 33 located on the outside of the body 10. When the drive switch 33 is driven, the drive switch 33 drives the valve core 31 to move in the inner core tube 20 through the valve stem 32.

[0045] In this embodiment, a receiving chamber 21 is formed on the water path of the inner core tube 20, and the valve core 31 is rotatably installed in the receiving chamber 21. The driving switch 33 is a knob 33, and the knob 33 drives the valve stem 32 to rotate, thereby driving the valve core 31 to rotate. The valve core 31 is rotatably arranged in the receiving chamber 21 to realize its control function, and the structure is simpler and more compact.

[0046] Specifically, the water path of the inner core tube 20 includes a water inlet water path 24, a receiving chamber 21, a top spray water path 25 and a side spray water path 26. The receiving chamber 21 includes an inlet (not shown) and two outlets (not shown), and the two outlets are respectively connected to the top spray water path 25 and the side spray water path 26. The valve core 31 is a switching valve core 31 and is arranged in the receiving chamber 21. By rotating the switching valve core 31, the water inlet water path 24 is switched to connect the top spray water path 25 and the side spray water path 26. The water outlet end of the top spray water path 25 is connected to the top spray shower (not shown), and the water outlet end of the side spray water path 26 is connected to the side spray water nozzle 60. The preferred control method is that the switching valve core 31 can control the top spray shower and the side spray water nozzle 60 to stop water at the same time or discharge water at the same time or only one of them discharges water, etc. Of course, the control valve of the utility model is not limited to a switching valve, it can also be a throttle valve or a mixing valve or a thermostatic valve, etc., and the specific function of the control valve is not limited.

[0047] In this embodiment, the control valve 30 further includes a screw 34. The valve core 31 is provided with a screw hole 311 facing the through hole 11. The valve stem 32 is provided with a central hole 321 penetrating therethrough. The screw 34 passes through the through hole 331 and the central hole 321 provided on the drive switch 33 and is threadedly connected with the screw hole 311. The head of the screw 34 abuts against the edge of the through hole 331 to axially connect the valve core 31, the valve stem 32 and the drive switch 33. The valve core 31, the valve stem 32 and the drive switch 33 are axially connected together by using one screw 34 at the same time. The structure is simple and compact, and the assembly is more convenient and quick.

[0048] In this embodiment, the inner core tube 20 includes a main body 22 and a gland 23. The main body 22 is formed with a concave cavity. The gland 23 covers the opening of the concave cavity to enclose the accommodating cavity 21. After the valve core 31 is installed in the concave cavity, the gland 23 covers and fixes the opening of the concave cavity to limit the valve core 31 in the accommodating cavity 21. The gland 23 is provided with an avoidance hole 231 for connecting the valve core 31 with the valve stem 32. In specific implementation, after the valve core 31 is installed in the concave cavity, the gland 23 is welded and fixedly connected to the main body 22, so that the connection strength between the two is more reliable and the sealing is better.

[0049] In this embodiment, a connecting ring 40 is further included. The connecting ring 40 is inserted into the through hole 11. The inner end of the connecting ring 40 extends into the body 10 and is threadedly connected to the peripheral wall of the avoidance hole 231. The outer end of the connecting ring 40 is provided with a flange located on the outside of the body 10 and abuts against the edge of the through hole 11. The inner core tube 20 is fixedly connected to the body 10 by the connecting ring 40. On the one hand, the inner core tube 20 can be fixed, and on the other hand, the avoidance hole 231 of the gland 23 can be accurately corresponding to the through hole 11 of the body 10.

[0050] In this embodiment, the valve core 31 and the valve stem 32 cooperate with each other in the avoidance hole 231, and the portion of the valve core 31 inserted into the avoidance hole 231 is sealed with the inner wall of the avoidance hole 231 by a seal 50. The seal 50 is specifically a sealing ring. Specifically, a convex rib 312 is provided at one end of the valve core 31 facing the valve stem 32 (i.e., the outer end face of the valve core 31), and a groove 323 is provided at one end of the valve stem 32 facing the valve core 31 (i.e., the inner end face of the valve stem 32). The transmission cooperation between the valve core 31 and the valve stem 32 is achieved by the engagement of the convex rib 312 and the groove 323. In addition, a spline 324 is provided at one end of the valve stem 32 away from the groove 323, and correspondingly, a spline 324 is provided at the knob 33, and the rotation linkage cooperation between the knob 33 and the valve stem 32 is achieved by the spline.

[0051] In this embodiment, the control valve 30 further includes a gasket 35, which is sandwiched between the knob 33 and the body 10. The gasket 35 can fill the gap between the knob 33 and the body 10, and can be made of wear-resistant material to effectively protect the appearance of the body 10 from being damaged by the friction of the knob 33.

[0052] In this embodiment, the outer peripheral wall of the valve stem 32 is provided with a plurality of gear grooves 322 along the circumferential direction, and also includes a pin seat 36 fixed on the outer side wall of the body 10, and a pin 37 is provided on the pin seat 36. When the valve stem 32 rotates, the pin 37 sequentially cooperates with the plurality of gear grooves 322. When the knob 33 is connected to the valve stem 32, the pin seat 36 extends into the inner cavity of the knob 33 to be covered by the knob 33, thereby preventing the pin seat 36 and the pin 37 from being exposed and affecting the appearance. The cooperation between the pin 37 and the gear groove 322 can remind the user of the gear position of the knob 33, making it more convenient to use. In this embodiment, a pin seat mounting hole 12 is also provided on the side wall of the body 10 near the through hole 11, and the pin seat 36 is fixed to the pin seat mounting hole 12 by screws.

[0053] In this embodiment, at least one end of the body 10 forms an opening, and the inner core tube 20 with the valve core 31 installed can be inserted into the body 10 through the opening as a whole. After the inner core tube 20 is inserted into place, the position of the valve core 31 corresponds to the position of the through hole 11. In this way, the inner core tube 20 that has passed the water sealing test can be directly installed into the body 10 with the valve core 31, and the assembly is more convenient, fast and reliable.

[0054] When assembling the present embodiment:

[0055] First, after the valve core 31 is covered with the sealing member 50, it is installed in the concave cavity of the main body 22 of the inner core tube 20, and then the pressure cover 23 is set at the opening of the concave cavity of the main body 22 by welding, so that the valve core 31 is sealed and installed in the inner core tube 20. The inner core tube 20 with the valve core 31 installed is inserted into the main body 10 as a whole. When the inner core tube 20 is inserted into place, the avoidance hole 231 of the pressure cover 23 of the inner core tube 20 corresponds to the position of the through hole 11 of the main body 10. At the same time, the position of the valve core 31 corresponds to the position of the through hole 11. The connecting ring 40 is penetrated into the through hole 11, and the inner end of the connecting ring 40 extends into the main body 10 and is threadedly connected with the peripheral wall of the avoidance hole 231. The outer end of the connecting ring 40 is provided with a flange located on the outside of the main body 10 and abuts against the edge of the through hole 11, so that the inner core tube 20 is fixedly connected to the main body 10 through the connecting ring 40;

[0056] Next, the groove 323 on the inner end surface of the valve stem 32 is aligned with the convex rib 312 on the outer end surface of the valve core 31, so that the valve stem 32 is in driving connection with the valve core 31;

[0057] Next, the elastic pin 37 is installed into the cavity of the elastic pin seat 36, and the elastic pin seat 36 with the elastic pin 37 installed is fixed to the elastic pin seat installation hole 12 by screws, so that the elastic pin 37 is matched with the gear groove 322 on the valve stem 32;

[0058] Then, the washer 35 is put on the periphery of the elastic pin seat 36, and the knob 33 is put on the valve stem 32, so that the inner end of the knob 33 abuts against the washer 35;

[0059] Finally, the screw 34 passes through the through hole 331 on the drive switch 33 and the center hole 321 on the valve stem 32 and is threadedly connected to the screw hole 311 of the valve core 31. The head of the screw 34 abuts against the edge of the through hole 331 to axially connect the valve core 31, the valve stem 32 and the drive switch 33 together. After the screw 34 is connected, a decorative sheet 38 covers the head of the screw 34, thereby completing the entire assembly process of the control valve.

[0060] The technical solution of the present invention is to separate the valve core 31 and the valve stem 32 of the control valve 30 so that when installing the control valve 30, the valve core 31 can be sealed and installed in the inner core tube 20 first, and then the valve stem 32 can be driven and matched with the valve core 31. In this way, the inner core tube 20 installed with the valve core 31 can be directly used for water sealing test independently, without using the main body 10 as the installation matching part of the control valve 30, so that the water sealing test does not need to be tested together with the main body 10, thereby effectively avoiding the problem of damage to the appearance of the main body 10 during the test, and the structure is simple and reliable. In addition, since the inner core tube 20 needs to withstand water pressure, a material with better strength can be selected, and the main body 10 of the utility model does not need to be used to withstand water pressure, so the material requirements are not high, and the range of selectable materials is wider. In the prior art, since the main body 10 is required to limit the installation of the control valve 30, the main body 10 needs to withstand the water pressure transmitted through the control valve 30, so the strength requirements for the main body 10 are generally greater. Otherwise, the main body 10 is easily deformed outward due to water pressure, resulting in poor appearance, and even interfering with the action of the control valve 30.
