Technical Field

[0001] The invention relates to the field of bathrooms, and in particular to a double-tube shower system with a liquid adding function. Background Art

[0002] The existing shower system mainly plays a role in cleaning and massage. With the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, and the requirements for bathing experience are also getting higher and higher. However, the existing shower head only has a simple water outlet function. The bathroom usually needs to place shower gel, shampoo and other products separately, which is not only inconvenient to use, but also takes up bathroom space. At present, some shower heads on the market have the function of adding fragrances or beauty essences. Generally, the required liquid is stored inside the handheld shower head. Such a design makes the shower head look bloated, and the liquid will run out quickly. After use, a new liquid barrel needs to be replaced, resulting in waste of materials. Frequent replacement is very cumbersome. Summary of the invention

[0018] Preferably, the shower head comprises a water outlet cavity connected to the first channel and a liquid outlet channel connected to the second channel.

[0019] The beneficial effects of the present invention are:

[0020] 1. A double-tube shower system with a liquid adding function of the present invention comprises: a water inlet channel connected to a water supply source; a hand-held shower head having a first channel and a second channel, wherein the first channel is connected to the water inlet channel; the hand-held shower head has an additional channel, but the structure is not increased much, and the previous design size can still be maintained without increasing the weight.

[0021] A control unit, used for controlling the opening and closing of the first channel;

[0022] The liquid adding unit is independently arranged from the handheld showerhead, and comprises a control channel, a liquid storage chamber and a movable part, wherein the control channel is communicated with the water inlet channel, and the liquid storage chamber is communicated with the second channel. When the first channel is closed, the control channel pushes the movable part to move under the action of the water pressure of the water inlet channel, and then the liquid storage chamber is compressed by the movable part to supply liquid to the second channel. The liquid adding unit is independently arranged from the handheld showerhead, and can be filled with and stored with more liquid, thereby extending the use time, reducing the frequency of replacement, and will not increase the handheld weight, and is easy to operate.

[0023] The shower head of this solution can realize both water discharge function and liquid supply function by setting up independent first channel and second channel. Bath gel or shampoo can be discharged through the second channel. The liquid supply function is stable and the structure is simple, which improves the user experience.

[0024] 2. It also includes an elastic member, and the liquid storage cavity can expand under the elastic force of the elastic member for the next cycle;

[0025] 3. It also includes an air supply channel connected to the liquid storage chamber and a one-way valve arranged on the air supply channel. Under normal conditions, the one-way valve closes the air supply channel. When the liquid storage chamber expands, the one-way valve opens the air supply channel, so that the liquid storage chamber is connected to the outside atmosphere, thereby preventing negative pressure from forming in the liquid storage chamber and preventing water from flowing back into the liquid storage chamber, causing the liquid in the liquid storage chamber to be diluted;

[0026] 4. The liquid adding unit comprises a cylinder body, the liquid storage chamber is formed in the cylinder body, and the movable part is a piston which is sealed and movable in the cylinder body, and has a simple structure and stable function;

[0027] 5. It also includes a limiting member disposed in the liquid storage cavity to limit the moving stroke of the movable member, thereby ensuring that the moving stroke of the movable member is consistent each time, thereby achieving the effect of quantitative liquid supply;

[0028] 6. The liquid adding unit is installed on the shower faucet, does not occupy the space of the handheld shower, reduces the weight of the handheld shower, and improves the user experience;

[0029] 7. The control unit includes a switching component, which controls the opening and closing of the first channel and the second channel. When the shower is discharging water, the first channel is opened and the second channel is closed; when the liquid is supplied, the first channel is closed and the second channel is opened. The alternating opening of the two channels can ensure that the shower hose is not pressurized and reduce the risk of pipe explosion;

[0030] Another control method is that the second channel is always in an open state under normal circumstances, and the switching member only controls the on and off of the first channel. When the first channel is opened, both channels are in an open state. Since the water flow needs to push the piston to work in the second channel, but not in the first channel, the pipe resistance is relatively small, and the water flow automatically chooses the first channel to pass water. When the first channel is closed, the water flow can only choose to pass water from the second channel, thereby pushing the piston and squeezing out the shower gel. This control method will not cause the hose to be pressurized, thereby reducing the risk of pipe bursting. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] like Figures 1 to 10 As shown, a double-pipe shower system with a liquid adding function comprises:

[0044] A water inlet channel 11 is connected to a water supply source;

[0045] The hand-held shower head 20 has a first channel 21 and a second channel 22, wherein the first channel 21 is connected to the water inlet channel 11. The hand-held shower head 20 has an additional channel, but the structure is not much increased, and the previous design size can still be maintained without increasing the weight;

[0046] A control unit 30, used to control the opening and closing of the first channel 21;

[0047] The liquid adding unit 40 is independently arranged from the hand-held shower 20, and includes a control channel 41, a liquid storage chamber 42 and a movable part 43, wherein the control channel 41 is connected with the water inlet channel 11, and the liquid storage chamber 42 is connected with the second channel 22. When the first channel 21 is closed, the control channel 41 pushes the movable part 43 to move under the water pressure of the water inlet channel 11, and then compresses the liquid storage chamber 42 through the movable part 43 to supply liquid to the second channel 22.

[0048] In this embodiment, an elastic member 44 is further included. When the first channel 21 is opened, the liquid storage chamber 42 can expand under the elastic force of the elastic member 44 for use in the next cycle. Specifically, the elastic member 44 adopts a return spring, and the water under the elastic member 44 flows back into the first channel 21.

[0049] In this embodiment, it also includes an air supply channel 45 connected to the liquid storage chamber 42 and a one-way valve 46 arranged on the air supply channel 45. Under normal circumstances, the one-way valve 46 closes the air supply channel 45. When the liquid storage chamber 42 expands, the one-way valve 46 opens the air supply channel 45, so that the liquid storage chamber 42 is connected to the external atmosphere, preventing negative pressure from forming in the liquid storage chamber 42, and preventing water from flowing back to the liquid storage chamber 42, resulting in dilution of the liquid in the liquid storage chamber 42.

[0050] In this embodiment, the liquid adding unit 40 includes a cylinder body 47, the liquid storage chamber 42 is formed in the cylinder body 47, and the movable part 43 is a piston 43 that is sealed and movable in the cylinder body 47, which has a simple structure and stable function.

[0051] In this embodiment, it also includes a limit member 48 arranged in the liquid storage chamber 42 to limit the moving stroke of the movable member 43 to ensure that the moving stroke of the movable member 43 is consistent each time, thereby achieving the effect of quantitative liquid supply; it also includes a liquid filling cover 49 that cooperates with the opening and closing of the cylinder body 47. The liquid filling cover 49 is opened to add liquid to the cylinder body 47. Specifically, the liquid filling cover 49 is threadedly connected to the cylinder body 47, and the air supply channel 45 is arranged on the liquid filling cover 49.

[0052] In this embodiment, a shower faucet 10 is further included. The water inlet channel 11 is arranged in the shower faucet 10. The shower faucet 10 is also provided with a first water outlet 12 connected to the first channel 21, and a second water outlet 13 connected to the control channel 41. Specifically, a connecting pipe 50 is also included. The connecting pipe 50 includes a water outlet pipe 51 and a liquid adding pipe 52 respectively connected to the first channel 21 and the second channel 22, wherein the water outlet pipe 51 is connected to the first water outlet 12 of the shower faucet 10 so that the first channel 21 is connected to the water inlet channel 11, and the liquid adding pipe 52 is connected to the cylinder body 47 and is connected to the liquid storage chamber 42.

[0053] In this embodiment, the liquid adding unit 40 is installed on the shower faucet 10. Specifically, the liquid adding unit 40 is installed at the second water outlet 13 of the shower faucet 10, does not occupy the space of the handheld shower 20, reduces the weight of the handheld shower 20, and improves the user experience.

[0054] In this embodiment, the control unit 30 includes a switching element 31, which controls the opening and closing of the first channel 21 and the second channel 22. When the shower is discharging water, the first channel 21 is opened and the second channel 22 is closed; when the liquid is supplied, the first channel 21 is closed and the second channel 22 is opened. The alternating opening of the two channels can ensure that the shower hose is not pressurized and reduce the risk of pipe explosion.

[0055] Another control method is that the second channel 22 is always in an open state under normal circumstances, and the switching member 31 only controls the on and off of the first channel 21. When the first channel 21 is opened, both channels are in an open state. Since the water flow needs to push the piston to work in the second channel 22, but not in the first channel 21, the pipe resistance is relatively small, and the water flow automatically chooses the first channel 21 to pass water. When the first channel 21 is closed, the water flow can only choose to pass water from the second channel 22, thereby pushing the movable member 43 to squeeze out the shower gel. This control method will not cause the hose to be pressurized, thereby reducing the risk of pipe bursting.

[0056] In this embodiment, the handheld shower 20 includes a shower head 20a and a shower handle 20b. The shower handle 20b is provided with a driving member 32 that cooperates with the switching member 31. Specifically, the driving member 32 is a knob sleeved on the shower handle 20b.

[0057] In this embodiment, the shower head 20a includes a water outlet cavity 23 connected to the first channel 21 and a liquid outlet channel 24 connected to the second channel 22. Specifically, the shower head 20a includes a water outlet panel 25, which is provided with a plurality of water outlet holes 251 connected to the water outlet cavity 23, and also includes a liquid outlet hole 252 connected to the liquid outlet channel 24.

[0058] The specific working process of this embodiment:

[0059] Under normal conditions, the switch 31 opens the first channel 21 and closes the second channel 22. At this time, the water in the water inlet channel 11 flows through the first water outlet 12 to the water outlet pipe, and the water in the water outlet pipe flows through the first channel 21 to the water outlet cavity 23 and then is sprayed out from the water outlet hole 251, realizing the shower function.

[0060] When the user needs to use shower gel or shampoo, the driving member 32 is rotated to drive the switching member 31 to close the first channel 21 and open the second channel 22. At this time, the water pressure of the water inlet channel 11 cannot be discharged from the first channel 21. The control channel 41 pushes the piston 43 to move under the action of the water pressure of the water inlet channel 11, and then the piston 43 compresses the liquid storage chamber 42 to supply liquid to the second channel 22 through the liquid adding pipe. The liquid in the second channel 22 flows out from the liquid outlet hole 252 through the liquid outlet channel 24 for use by the user.

[0061] After switching back to open the first channel 21 , the water pressure of the water inlet channel 11 is released through the first channel 21 , and then the piston 43 is reset under the action of the elastic member 44 . During the reset process, the liquid storage chamber 42 is replenished with air through the air replenishment channel 45 .

[0062] The shower head of the present invention can realize both the water outlet function and the liquid supply function by setting up the independent first channel 21 and the second channel 22. Bath gel or shampoo etc. can be discharged through the second channel 22, and the liquid supply function is stable and the structure is simple, thereby improving the user experience.

[0063] When the shower is discharging water, the first channel 21 is opened and the second channel 22 is closed; when supplying liquid, the first channel 21 is closed and the second channel 22 is opened. The alternating opening of the two channels can ensure that the shower hose is not pressurized and reduce the risk of pipe explosion. The handheld shower 20 has an additional channel, but the structure is not increased much, and the previous design size can still be maintained without increasing the weight. In addition, the liquid adding unit 40 is independently arranged from the handheld shower 20, and more liquid can be added and stored, which prolongs the use time and reduces the frequency of replacement. It will not increase the handheld weight and is easy to operate.

[0064] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
