Description

Technical Field

[0001] The utility model relates to a shower valve. Background Art

[0002] A Chinese patent document with publication number CN105395115A discloses a shower with bath liquid, including a water diverter, a liquid inlet, and a bath bottle; the water diverter is installed in the middle of the shower rod, the liquid inlet is installed on the water diverter and communicated with the inner cavity of the water diverter, and the bath bottle is installed on the top of the liquid inlet and communicated with the inner cavity of the liquid inlet. Since the present invention has a liquid inlet on the shower rod of the traditional shower equipment, the liquid inlet is connected to the bath bottle, and the bath bottle continuously feeds shower gel / shampoo into the liquid inlet. By pulling the upper rod of the liquid inlet, the shower gel / shampoo can be fed into the shower rod and enter the shower channel, forming mixed water with shower gel / shampoo and transporting it to the shower head or overhead spray. At this time, the water from the overhead spray is mixed water with shower gel / shampoo. There is no need to apply shower gel / shampoo during bathing, and a new shower can be experienced. As the bathing time goes by, the mixed water is replaced by the original water and rinsed clean.

[0003] However, in the above scheme, the shower gel / shampoo in the shower channel needs to be used up before clean water can be discharged. If the user only needs to use a small amount of shower gel / shampoo, it is necessary to wait for the shower gel / shampoo to be rinsed off, which is inconvenient to use. In addition, the shower bottle in the above scheme needs to be placed upside down on the shower device, which is inconvenient to load and unload and is easy to leak. Utility Model Content

[0004] The utility model aims to provide a shower valve which is easy to operate and can discharge cleaning liquid.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A shower valve comprises a shell, characterized in that it also comprises a storage tank and a diverter box, the storage tank is used to store cleaning liquid, the diverter box is arranged in the shell, a drainage joint is arranged on the shell, a first drainage channel and a second drainage channel are arranged in the shell, a first control valve for controlling the on-off of the first drainage channel and a second control valve for controlling the on-off of the second drainage channel are arranged on the shell, the first drainage channel is connected to the drainage joint, the diverter box comprises a first fluid channel and a second fluid channel, one end of the first fluid channel is connected to the second drainage channel, and the other end is connected to the drainage joint, one end of the second fluid channel is connected to the storage tank, and the other end is connected to the first fluid channel, the first fluid channel comprises a drainage section, the cross-sectional area of ​​the drainage section is much smaller than the cross-sectional area of ​​other parts of the first fluid channel, and the second fluid channel is connected to the side of the drainage section.

[0007] When the user takes a shower, he presses the second control valve, and water will flow from the second drainage channel into the first fluid channel of the diversion box. The cross-sectional area of ​​the drainage section is much smaller than that of other parts, so the flow rate of the drainage section is faster. According to the Venturi effect, the second fluid channel will be attracted by the drainage section, and the cleaning fluid in the storage tank will be sucked out and flow into the first fluid channel to mix with clean water, and then discharged through the drainage joint. The user does not need to apply additional cleaning fluid, and can close the second control valve at any time according to the user's needs and then press the first control valve to switch to clean water for bathing at any time, which is easy to operate; when the user needs to use clean water for bathing, press the first control valve, and the clean water can pass through the first drainage channel and flow out from the drainage joint, and the cleaning fluid will not flow out.

[0008] The cross-sectional area of ​​the drainage section is one tenth to one third of the cross-sectional area of ​​other parts of the first fluid channel, so that a faster flow rate can be achieved in the drainage section, and the cleaning liquid can be smoothly sucked out. If the ratio is too small, the cleaning liquid may not be able to flow smoothly into the drainage section. If the ratio is too large, the water flow rate in the drainage section is small, and it is difficult to suck out the cleaning liquid.

[0009] The drainage section extends in a straight line, and the second fluid channel includes a conducting section, which is vertically connected to the drainage section. Compared with a curved extension, a straight-line extension of the drainage section can better achieve a higher water flow rate, and the conducting section is vertical to the drainage section, which can better achieve the cleaning fluid being sucked out of the second fluid channel.

[0010] The cross-sectional area of ​​the conduction section is smaller than that of the drainage section. If the cross-sectional area of ​​the conduction section is larger than that of the drainage section, the pressure relief effect of the water flow through the drainage section on the conduction section is not strong enough to suck out the cleaning liquid.

[0011] The diversion box includes a bottom plate, an outer plate, a partition plate and a top plate. The bottom plate and the top plate are arranged parallel to each other, the outer plate is arranged between the outer edges of the bottom plate and the top plate, and the partition plate is arranged between the bottom plate and the top plate to divide the interior of the diversion box into the first fluid channel and the second fluid channel.

[0012] The bottom plate, the outer plate and the partition plate are integrally formed, and the integral forming can make the sealing between the bottom plate, the outer plate and the partition plate stronger and facilitate production.

[0013] The drain joint passes through the diverter box up and down, and a connecting hole located in the diverter box is formed on the outer side of the drain joint. The first fluid channel is connected to the drain joint through the connecting hole, so that water in the second drain channel can pass through the diverter box and be discharged from the drain joint through the connecting hole.

[0014] The storage tank is arranged in the shell, and a clearance hole is formed on the storage tank, and a liquid extraction pipe is provided. The liquid extraction pipe includes a suction section, a connecting section and a discharge section. The suction section extends up and down through the clearance hole and extends into the interior of the storage tank, and the discharge section is connected with the second fluid channel. The connecting section is connected between the discharge section and the suction section. When a high-speed water flow passes through the drainage section, a negative pressure will be formed in the second fluid channel. At this time, the cleaning liquid in the storage tank will be sucked out, flow upward from the suction section and flow into the second fluid channel through the connecting section and the discharge section. Because the suction section is extended up and down, when the drainage section does not pass through the high-speed water flow, the cleaning liquid in the storage tank will not flow into the second fluid channel, and will not cause waste.

[0015] A water channel integrated module is disposed in the housing, and the first drainage channel and the second drainage channel are formed in the water channel integrated module. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figures 1 to 10As shown, a shower valve comprises a shell 1, in which a storage tank 4, a diverter box 2 and a water channel integrated module 3 are arranged. The storage tank 4 is used to store cleaning liquid. A feeding port 44 is formed at the upper end of the storage tank 4. A through hole opposite to the feeding port is formed at the upper end of the shell 1, and a sealing top cover 14 for covering the feeding port 44 and the perforation is provided. The cleaning liquid can be shower gel or shampoo, and the user can add it through the feeding port 44.

[0027] The rear end of the water channel integrated module 3 is provided with a hot water connector 31 and a cold water connector 32, which extend out of the rear end of the shell 1. The water channel integrated module 3 forms a water inlet mainstream channel 34 and a water outlet mainstream channel 35. The hot water connector 31 and the cold water connector 32 are connected to the water inlet mainstream channel 34. The water channel integrated module 3 also forms a water mixing chamber 33, which is connected to the water inlet mainstream channel 34 and the water outlet mainstream channel 35. Hot water and cold water flow from the hot water connector 31 and the cold water connector 32 into the water inlet mainstream channel 34. Then enter the mixing water chamber 33, where a temperature regulating device 37 is provided. A knob 13 connected to the temperature regulating device 37 is provided at the front end of the shell 1. The water temperature can be adjusted by operating the knob 13. The adjusted water then flows from the mixing water chamber 33 into the main outlet water channel 35. The temperature regulating device 37 and the knob 13 are already disclosed in the prior art and are not described in detail herein. The waterway integrated module 3 also forms a plurality of branch channels 36 connected to the main outlet water channel 35, and the water in the main outlet water channel 35 is discharged through the branch channels 36.

[0028] The diverter box 2 is arranged in the housing 1, and a drain connector 5 extending from the lower end of the housing 1 is arranged at the lower end of the water channel integrated module 3. The water channel integrated module 3 is provided with a first drain channel 61 and a second drain channel 62. The first drain channel 61 and the second drain channel 62 are both the above-mentioned tributary channels 36. The front end of the housing 1 is provided with a first control valve 11 for controlling the on-off of the first drain channel 61 and a second control valve 12 for controlling the on-off of the second drain channel 62. The first drain channel 61 is connected to the drain connector 5. The diverter box 2 includes a first fluid channel 25 and a second fluid channel 26. One end of the first fluid channel 25 is connected to the second drain channel 62 through the water inlet connector 27, and the other end is connected to the drain connector 5. One end of the second fluid channel 26 is connected to the storage tank 4, and the other end is connected to the first fluid channel 25. The first fluid channel 25 includes a drainage section 251. The cross-sectional area of ​​the drainage section 251 is much smaller than the cross-sectional area of ​​other parts of the first fluid channel 25. The second fluid channel 26 is connected to the side of the drainage section 251. The drain connector 5 can be connected to a shower.

[0029] When the user takes a shower, he presses the second control valve 12, and water will flow from the second drainage channel 62 into the first fluid channel 25 of the diversion box 2. The cross-sectional area of ​​the drainage section 251 is much smaller than that of other parts, so the flow rate of the drainage section 251 is faster. According to the Venturi effect, the second fluid channel 26 will be attracted by the drainage section 251, and the cleaning liquid in the storage tank 4 will be sucked out and flow into the first fluid channel 25 to mix with the clean water, and then discharged through the drainage connector 5. The shower head or overhead spray can produce water mixed with the cleaning liquid, and the user does not need to apply additional cleaning liquid. The user can also close the second control valve 12 at any time according to the user's needs and then press the first control valve 11 to switch to clean water for bathing at any time, which is easy to operate. When the user needs to use clean water for bathing, press the first control valve 11, and the clean water can pass through the first drainage channel 61 and flow out from the drainage connector 5, and the cleaning liquid will not flow out.

[0030] The cross-sectional area of ​​the drainage section 251 is one tenth to one third of the cross-sectional area of ​​the other parts of the first fluid channel 25, so that the flow rate of the drainage section 251 can be faster and the cleaning liquid can be sucked out smoothly. If the ratio is too small, the cleaning liquid may not flow smoothly into the drainage section 251. If the ratio is too large, the water flow rate of the drainage section 251 is small, and it is difficult to suck out the cleaning liquid. The drainage section 251 extends straight, and the second fluid channel 26 includes a conduction section 261, which is vertically connected to the drainage section 251. Compared with the curved extension, the straight extension of the drainage section 251 can better achieve a higher water flow rate, and the conduction section 261 is perpendicular to the drainage section 251, which can better achieve the cleaning liquid being sucked out of the second fluid channel 26. The cross-sectional area of ​​the conducting section 261 is smaller than that of the drainage section 251 . If the cross-sectional area of ​​the conducting section 261 is larger than that of the drainage section 251 , the water flow through the drainage section 251 will not have a strong enough pressure relief effect on the conducting section 261 , and the cleaning liquid cannot be sucked out.

[0031] The flow dividing box 2 is composed of a bottom plate 21, an outer plate 22, a partition plate 23 and a top plate 24. The bottom plate 21 and the top plate 24 are arranged parallel to each other. The outer plate 22 is arranged between the outer periphery of the bottom plate 21 and the top plate 24. The partition plate 23 is arranged between the bottom plate 21 and the top plate 24 to divide the inside of the flow dividing box 2 into a first fluid channel 25 and a second fluid channel 26. The bottom plate 21, the outer plate 22 and the partition plate 23 are integrally formed. The integral forming can make the sealing between the bottom plate 21, the outer plate 22 and the partition plate 23 stronger and facilitate production. The top plate 24 and the outer plate 22 can be connected by friction welding to enhance the sealing, and of course, they can also be connected by bolts or glue.

[0032] The drain connector 5 passes through the diverter box 2 up and down, and a connecting hole 51 is formed on the outer side of the drain connector 5, which is located in the diverter box 2. The first fluid channel 25 is connected to the drain connector 5 through the connecting hole 51, so that the water in the second drain channel 62 can pass through the diverter box 2 and be discharged from the drain connector 5 through the connecting hole 51.

[0033] A clearance hole 42 is formed on the storage tank 4, and a liquid extraction tube 43 connected to the diverter box 2 is provided. The liquid extraction tube 43 includes a suction section 431, a connecting section 432 and a discharge section 433. The suction section 431 extends up and down through the clearance hole 42 and extends into the storage tank 4. The discharge section 433 is connected to the second fluid channel 26. The connecting section 432 is connected between the discharge section 433 and the suction section 431. When a high-speed water flow passes through the drainage section 251, a negative pressure will be formed in the second fluid channel 26. At this time, the cleaning liquid in the storage tank 4 will be sucked into the suction section 431, flow upward from the suction section 431 and flow into the second fluid channel 26 through the connecting section 432 and the discharge section 433. Because the suction section 431 is extended up and down, when the drainage section 251 does not pass through the high-speed water flow, the cleaning liquid in the storage tank 4 will not flow into the second fluid channel 26, and will not cause waste.

[0034] The shell 1 is also provided with a plurality of switch valves for controlling the on-off of the branch channels 36 other than the first drainage channel 61 and the second drainage channel 62. These branch channels 36 can be connected to shower tools such as shower heads, overhead sprays or spray guns, making the utility model more versatile. One of the branch channels 36 is connected to a waterfall-type water outlet 38 arranged at the lower end of the shell 1. The waterfall-type water outlet is long and has a plurality of water outlet holes arranged at intervals along its length. The lower end of the shell 1 is formed with a long hole for the waterfall-type water outlet 38 to extend out. The water outlet of the waterfall-type water outlet 38 can be in a waterfall shape, which increases the aesthetics. In addition, a groove for hanging a shower is formed on the side of the shell 1, further increasing the versatility of the utility model.

[0035] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
