Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bathroom products, in particular to a water outlet device and a shower device. BACKGROUND

[0002] In the conventional shower mode, the user usually needs to close the shower head before applying shower gel (body wash or shampoo), but in a low-temperature environment, turning off the hot water will make the user feel very cold. In the related art, a liquid storage box is arranged in the shower device, which is used to contain shower gel and is in communication with the shower head, so as to directly deliver the shower gel to the shower head to be sprayed together with hot water to the user's body to form foam. In order to continuously discharge the shower gel, the piston needs to be moved towards the liquid outlet to squeeze the shower gel. In order to ensure that all the shower gel in the liquid storage box can be discharged, the piston needs to have a certain stroke, especially when there is a large amount of shower gel, the piston stroke is large, so that the size of the liquid storage box is large. SUMMARY

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a water outlet device which can use the reciprocating motion of the piston to increase the air pressure in the liquid storage box to discharge the shower gel, and has a more compact structure and smaller size.

[0004] The present application also provides another water outlet device.

[0005] The present application also provides a shower device having the above water outlet device.

[0006] According to the water outlet device of the first aspect of the present application, the water outlet device comprises:

[0007] a main body having a containing cavity, a pressurizing cavity, a water inlet, a water outlet, an air inlet, a first channel and a second channel, the containing cavity is used to store shower gel, one end of the first channel is in communication with the water inlet, and the other end is in communication with the water outlet, one end of the second channel is in communication with the containing cavity, and the other end is in communication with the first channel, the pressurizing cavity is in communication with the containing cavity, and the air inlet is in communication with the containing cavity and an external space;

[0008] a first check valve arranged in the second channel;

[0009] a second check valve arranged at the air inlet, and air in the external space can enter the containing cavity through the second check valve;

[0010] a pressurizing assembly comprising a first driving mechanism and a piston, the piston is arranged in the pressurizing cavity and abuts against the side wall of the pressurizing cavity, the first driving mechanism is connected to the piston and used to drive the piston to move close to or away from the containing cavity, so that the piston reciprocates;

[0011] When the piston moves toward the receiving cavity, the air pressure in the receiving cavity increases, and the shower liquid in the receiving cavity is squeezed to the first check valve. The first check valve is opened under pressure, and the shower liquid in the receiving cavity can flow into the first channel through the second channel.

[0012] The water outlet device according to embodiments of the present invention has at least the following beneficial effects:

[0013] The first drive mechanism drives the piston to reciprocate. When the piston moves toward the receiving cavity, it increases the air pressure in the cavity, thus forcing the shower liquid into the second channel. When the piston moves in the reverse direction, a negative pressure is generated in the receiving cavity, allowing air to enter through the second check valve, making the air pressure in the receiving cavity the same as the outside air pressure. Therefore, the water outlet device in this embodiment can continuously discharge shower liquid from the receiving cavity using air pressure through the reciprocating motion of the piston, without requiring a large stroke of the piston in one direction. This allows the overall size of the water outlet device to be made smaller, reducing the manufacturing cost of the water outlet device in this embodiment, while improving its applicability.

[0014] According to some embodiments of the present invention, the first drive mechanism includes a first cam, a first rotating rod, and a first turbine. The first cam and the first turbine are connected to the first rotating rod, which is rotatably disposed in the first channel. The end of the piston facing away from the receiving cavity abuts against the first cam. Water flowing through the first channel can drive the first turbine to rotate, thereby driving the first cam to rotate, so as to make the piston reciprocate.

[0015] According to some embodiments of the present invention, the first drive mechanism further includes an elastic element, one end of which is connected to the piston and the other end of which is connected to the body, so as to apply an elastic force away from the receiving cavity to the piston.

[0023] A water outlet device according to a second aspect embodiment of the present invention includes:

[0024] The main body includes a liquid storage box, a first tube, and a second tube. The liquid storage box has a receiving cavity and an air inlet. The receiving cavity is used to store shower liquid, and the air inlet is used to connect the receiving cavity with an external space. The first tube has a first channel, and an inlet and an outlet connected to the first channel. The second tube is made of a soft material and has a second channel. One end of the second channel is connected to the receiving cavity, and the other end is connected to the first channel.

[0025] The first check valve is located in the second channel;

[0026] The second check valve is located at the air inlet, allowing air from the outside space to enter the receiving cavity through the second check valve.

[0027] The extrusion assembly includes a second cam and a second drive mechanism. The second cam is disposed on the side of the second tube body, and the second drive mechanism is connected to the second cam to drive the second cam to rotate, so that the second cam extrudes the second tube body.

[0028] When the second cam squeezes the second tube, the shower liquid inside the second tube is squeezed to the first check valve, the first check valve is opened under pressure, and the shower liquid flows to the first channel through the first check valve.

[0029] The water outlet device according to embodiments of the present invention has at least the following beneficial effects:

[0030] This embodiment includes a second driving mechanism and a second cam. The second cam is disposed on the side of the second tube body. The driving device drives the second cam to rotate, thereby squeezing the second tube body. When the second tube body is squeezed, the shower liquid inside the second tube body can be squeezed to the first check valve. The first check valve opens under pressure, and the shower liquid flows to the first channel through the first check valve. Therefore, this embodiment utilizes the periodic squeezing of the second tube body by the second cam to continuously squeeze the shower liquid in the receiving cavity into the first channel. This eliminates the need for a large stroke of the piston in one direction, allowing the overall size of the water outlet device to be made smaller, reducing the manufacturing cost of the water outlet device in this embodiment, while also improving its applicability.

[0031] According to some embodiments of the present invention, the second drive mechanism includes a second rotating rod and a second turbine. One end of the second rotating rod is located inside the first channel and connected to the second turbine, and the other end is located outside the first channel and connected to the second cam. Water flowing through the first channel can drive the second turbine to rotate, thereby driving the second cam to rotate.

The water outlet device further includes a first valve, the first valve including a first valve core, the first valve core being located at the connection between the third channel and the first channel, the first valve core being capable of being driven to open or close the first channel.

[0039] The shower device according to embodiments of the present invention has at least the following beneficial effects:

[0040] The water outlet device according to the first aspect embodiment has an internal cavity for storing shower liquid, such as shampoo or shower gel. The shower liquid passes through a second channel and is foamed by a foaming component. After foaming, it is discharged from the outlet along with hot water and sprayed onto the user by the shower head, thus preventing the shower liquid from being directly washed away by the hot water and improving the foaming effect. Furthermore, the foaming component is located downstream of the connection between the second and first channels, so the shower liquid is mixed with water first and then foamed by the foaming component, thereby improving the foaming effect.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0059] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0060] Figure 1 This is a schematic diagram of the structure of a water outlet device according to an embodiment of the present invention. Figure 3 This is another structural diagram of the main body, for reference. Figure 1 and Figure 3 The water outlet device of the first aspect embodiment includes: a main body 100, a first check valve 200, a pressurization component 400, and a second check valve 500.

[0061] The main body 100 includes a receiving cavity 110, a water inlet 140, a water outlet 150, a first channel 120, and a second channel 130. The receiving cavity 110 is used to store shower liquid (such as shower gel, shampoo, etc.). The water inlet 140 is used to connect to a water supply device. One end of the first channel 120 is connected to the water inlet 140, and the other end is connected to the water outlet 150, for supplying water for user use. One end of the second channel 130 is connected to the receiving cavity 110, and the other end is connected to the first channel 120. A first check valve 200 is disposed within the second channel 130, and a second check valve 500 is disposed at the air inlet 170. The air inlet 170 connects the receiving cavity 110 to the external space, allowing air to enter the receiving cavity 110 through the second check valve 500. A pressurization chamber 160 is connected to the receiving cavity 110. The pressurization assembly 400 includes a piston 410 and a first drive mechanism 420. The piston 410 is disposed within the pressurization chamber 160 and abuts against the side wall of the pressurization chamber 160. The first drive mechanism 420 drives the piston 410 to reciprocate. Therefore, during operation, when the piston 410 moves toward the receiving cavity 110, it increases the air pressure in the receiving cavity 110, thereby forcing the bathing liquid in the receiving cavity 110 into the second channel 130. When the piston 410 moves in the reverse direction, a negative pressure is generated in the receiving cavity 110, allowing air to enter the receiving cavity 110 through the second check valve 500, thus making the air pressure in the receiving cavity 110 the same as the external air pressure. The first check valve 200 prevents water in the first channel 120 from being drawn back into the second channel 130. The reciprocating motion of the piston 410 continuously pressurizes the shower liquid in the receiving cavity 110 into the second channel 130. In this embodiment, the piston 410 of the water outlet device reciprocates, continuously drawing outside air into the receiving cavity 110. Therefore, the volume of the pressurizing cavity 160 can be made smaller, resulting in a smaller overall size of the water outlet device in this embodiment, reducing manufacturing costs, and improving applicability.

[0062] Furthermore, the water outlet device of this embodiment allows for greater flexibility in the placement of the piston 410. As long as the internal air pressure of the receiving cavity 110 can be increased, there is no need to limit the direction of movement of the piston 410. This makes the design of the water outlet device of this embodiment simpler and lower in cost. Moreover, the position of the piston 410 can be set according to actual usage requirements, thereby improving the adaptability of the water outlet device of this embodiment to the environment and thus enhancing its applicability.

[0063] The main body 100 may also be provided with a feeding port 190, which is connected to the receiving cavity 110 for adding shower liquid into the receiving cavity 110. The main body 100 may also include a cover 800, which is detachably connected to the feeding port 190, and an air inlet 170 may be provided on the cover 800.

[0064] Reference Figure 1 and Figure 2, Figure 2 for Figure 1 A schematic diagram of the booster assembly 400 shows that in some embodiments, the end of the booster chamber 160 facing away from the receiving chamber 110 is connected to the first channel 120. The first drive mechanism 420 includes a first cam 421, a first rotating rod 422, and a first turbine 423. The first cam 421 and the first turbine 423 are connected to the first rotating rod 422, which is rotatably disposed within the first channel 120. The end of the piston 410 facing away from the receiving chamber 110 extends into the first channel 120 and abuts against the first cam 421. Water flowing through the first channel 120 impacts the first turbine 423, driving it to rotate. The first turbine 423 drives the first rotating rod 422 to rotate, thereby driving the first cam 421 to rotate, causing the piston 410 to reciprocate. Therefore, the water outlet device in this embodiment does not require an additional drive motor to drive the piston 410, saving manufacturing costs.

[0065] In addition, the water outlet device may be equipped with a locking element that can move relative to the main body 100 to press against the first turbine 423, thereby locking the first turbine 423. When shower liquid is not needed, locking the first turbine 423 allows clean water to be discharged from the water outlet 150 for the user's use.

[0066] Reference Figure 1 Based on the above embodiments, the first driving mechanism 420 further includes an elastic element 430, which can be a compression spring. One end of the elastic element 430 is connected to the piston 410, and the other end is connected to the main body 100. The connection between the elastic element 430 and the piston 410 is located on the side of the connection between the elastic element 430 and the main body 100 that faces away from the receiving cavity 110. When the piston 410 moves toward the receiving cavity, the elastic element 430 is compressed to apply a spring force away from the receiving cavity 110 to the piston 410. The elastic element 430 is a tension spring. One end of the elastic element 430 is connected to the piston 410, and the other end is connected to the main body 100. The connection between the elastic element 430 and the piston 410 is located on the side of the connection between the elastic element 430 and the main body 100 closer to the receiving cavity 110. When the piston 410 moves toward the receiving cavity, the elastic element 430 is stretched to apply a spring force away from the receiving cavity 110 to the piston 410, so that the piston 410 quickly returns to its original position to improve the shower liquid discharge speed and meet the user's needs.

[0067] Reference Figure 1 and Figure 3In some embodiments, the main body 100 further includes a third channel 180. A third pipe 181 can be disposed inside the main body 100. The third channel 180 is located inside the third pipe 181. One end of the third pipe 181 is connected to the side of the first pipe 121 near the inlet 140, and the other end is connected to the side of the first pipe 121 near the outlet 150. That is, one end of the third channel 180 is connected to the first channel 120, and the other end is connected to the outlet 150. The water outlet device also includes a first valve 900, which includes a first valve core 910. The first valve core 910 is disposed at the connection between the third channel 180 and the first channel 120. The first valve core 910 can be driven to move to open or close the first channel 120. When the first channel 120 is open, water can flow from the first channel 120 to the outlet 150, and the first turbine 423 is driven to rotate. When the first channel 120 is closed, water flows through the third channel 180 to the outlet 150. The first turbine 423 locks, stopping shower liquid from entering the first channel 120 to meet the user's need for clean water. Furthermore, the water flows through the third channel 180 to the outlet 150 to prevent the first turbine 423 from creating resistance to the water flow when using clean water, thereby increasing the pressure of the water flowing out of the outlet 150. It should be noted that the first valve core 910 is a common water circuit switching valve core, which will not be described in detail here.

[0068] Reference Figure 4 and Figure 5 , Figure 4 for Figure 3 An explosion diagram of the first valve 900 in the middle. Figure 5 for Figure 4 A cross-sectional view of the knob 930. Based on the above embodiment, the first valve 900 further includes a knob 930 and a connector 920. One end of the connector 920 is connected to the first valve core 910, and the other end has a latch 921 (e.g., ...). Figure 4 (As shown). The knob 930 also has a slot 932, and a latch 921 is engaged in the slot 932, with the latch 921 abutting against the peripheral wall of the slot 932. This allows the knob 930 to drive the connector 920 to rotate, thereby driving the first valve core 910. The knob 930 connector 920 does not require screws for connection, reducing manufacturing costs, and the knob 930 does not require drilling, making its appearance more aesthetically pleasing. Alternatively, the knob 930 may have a connecting hole 931, with a circumferentially extending slot 932 on the hole wall, and an axially extending limiting portion 933 (e.g., ...). Figure 5 As shown), the connector 920 also has a limiting groove 922 (as shown). Figure 4As shown, the buckle 921 extends into the connecting hole 931 and engages with the limiting groove 922. The limiting part 933 engages with the limiting groove 922 to restrict the knob 930 from rotating relative to the connector 920, thereby allowing the connector 920 to rotate with the knob 930.

[0069] Reference Figure 3 In some embodiments, the water outlet device further includes a second valve 950, which includes a second valve core disposed in the second channel 130 to adjust the opening and closing degree of the second channel 130, thereby controlling the amount of shower liquid entering the first channel 120 to meet the user's needs and improve the applicability of this embodiment. It should be noted that the second valve core is a common flow control valve core, which will not be described in detail here.

[0070] Reference Figure 1 and Figure 6 , Figure 6 for Figure 1 A schematic diagram of the receiving component 700. In some embodiments, the water outlet device further includes a receiving component 700, which has a receiving groove 710, an inlet 720 communicating with the receiving groove 710, and a flushing outlet 730. The receiving component 700 is connected to the main body 100 and located within the first channel 120. The inlet 720 communicates with the second channel 130, and the flushing outlet 730 is located within the first channel 120. Shower liquid conveyed through the second channel 130 can enter the receiving groove 710 through the inlet 720, and water flow in the first channel 120 can enter the receiving groove 710 through the flushing outlet 730 to flush the shower liquid located in the receiving groove 710, thereby increasing the mixing degree of the shower liquid and water and enhancing the foaming effect.

[0071] In some embodiments, the bottom wall of the receiving cavity 110 has an inclined surface, and the second channel 130 communicates with the receiving cavity 110 at the bottom wall of the receiving cavity 110 and at the lowest edge of the receiving cavity 110, so that the shower liquid in the receiving cavity 110 can be drained, preventing shower residue from causing liquid waste.

[0072] In some embodiments, the water outlet device further includes a foaming element 300, which is located within the first channel 120 and downstream of the connection between the second channel 130 and the first channel 120, along the flow direction of water within the first channel 120. When shower liquid is used, the first check valve 200 opens, allowing the shower liquid in the receiving cavity 110 to flow into the first channel 120 via the second channel 130. It mixes with the water in the first channel 120, then foams through the foaming element 300. After foaming, it is discharged from the outlet along with hot water and sprayed onto the user by the shower head, thereby preventing the shower liquid from being directly washed away by the hot water and improving the foaming effect.

[0073] Furthermore, since the foaming of shower liquid is mainly due to the action of foaming agents, the foaming agents reduce the interfacial tension at the air-water interface, causing air to form small bubbles in the shower liquid, thereby expanding the separation interface and ensuring that the bubbles rise to form a foam layer. The foaming process involves the hydrophilic groups in the foaming agent inserting into the aqueous phase and the lipophilic groups inserting into the oil phase or standing upright in the air, forming a directional arrangement on the interface layer or surface, thus reducing the interfacial tension or surface tension. When there is insufficient water or the water volume is inadequate, the hydrophilic groups in the foaming agent cannot insert into the water, resulting in poor foaming. Therefore, in the water outlet device of this embodiment, along the flow direction of water in the first channel 120, the foaming element 300 is located downstream of the connection between the second channel 130 and the first channel 120. When using the water outlet device of this embodiment, the shower liquid is mixed with water before entering the foaming element 300 for foaming, resulting in a better foaming effect.

[0074] The water outlet device of the second aspect embodiment includes a main body 100, a first check valve 200, a squeezing assembly, and a second check valve 500.

[0075] The main body 100 includes a storage box 111, a first pipe 121, and a second pipe 131. The storage box 111 has a receiving cavity 110 and an air inlet 170 communicating with the receiving cavity 110. The receiving cavity 110 is used to store shower liquid (such as shower gel, shampoo, etc.). The first pipe 121 has a first channel 120, and a water inlet 140 and an outlet 150 communicating with the second channel 130. The water inlet 140 is used to communicate with a water supply device, and the water outlet 150 is used to discharge water for user use. One end of the second channel 130 is connected to the receiving cavity 110, and the other end is connected to the first channel 120. A first check valve 200 is disposed within the second channel 130. A second check valve 500 is disposed at the air inlet 170, which connects the receiving cavity 110 to the external space, allowing air to enter the receiving cavity 110 through the second check valve 500.

[0076] The extrusion assembly includes a second cam and a second drive mechanism. The second cam is disposed on the side of the second tube 131, and the second drive mechanism is connected to the second cam to drive the second cam to rotate, causing the second cam to extrude the second tube 131. Because a second check valve 500 is provided at the air inlet 170, when the second cam extrudes the second tube 131, the air pressure in the receiving cavity 110 will prevent the shower liquid in the second channel 130 from entering the receiving cavity 110. Therefore, when the second cam extrudes the second tube 131, the shower liquid in the second channel 130 will be extruded to the first check valve 200, which will open under pressure, allowing the shower liquid to flow through the first check valve 200 to the first channel. When the second cam separates from the second tube 131, the wall of the second tube 131 returns to its original position, creating a negative pressure in the second channel 130. Due to the presence of the first check valve 200, water in the first channel 120 is not drawn into the second channel 130. Therefore, when a negative pressure is generated in the second channel 130, the shower liquid in the receiving cavity 110 is drawn into the second channel 130. Furthermore, outside air enters the receiving cavity 110 through the second check valve 500, preventing the negative pressure in the receiving cavity 110 from hindering the shower liquid from entering the second channel 130, thus ensuring smooth flow of the shower liquid into the second channel 130. This embodiment utilizes the periodic compression of the second tube 131 by the second cam to continuously compress the shower liquid in the receiving cavity 110 into the second channel 130 and flow towards the first channel 120. This eliminates the need for a piston with a large stroke in one direction, allowing for a smaller overall size of the water outlet device, reducing manufacturing costs, and improving applicability.

[0077] Furthermore, it is understood that by using the second cam to squeeze the second tube, the shower liquid in the receiving cavity can be discharged into the first channel without the need for a piston and a pressurizing chamber, making the water outlet device structure of this embodiment simpler, lower in cost, and easier to clean.

[0078] Based on the above embodiment, the second drive mechanism includes a second rotating rod and a second turbine. One end of the second rotating rod is located inside the first channel 120 and connected to the second turbine, while the other end is located outside the first channel 120 and connected to the second cam. Water flowing through the first channel 120 can drive the second turbine to rotate, thereby causing the second cam to rotate, so that the second cam periodically squeezes the second tube 131. Therefore, the water outlet device of this embodiment does not require an additional drive motor, thus saving manufacturing costs.

[0079] In some embodiments, the main body 100 further includes a third pipe 181 having a third channel. One end of the third pipe 181 is connected to the side of the first pipe 121 near the inlet 140, and the other end is connected to the side of the first pipe 121 near the outlet 150. That is, one end of the third channel 180 is connected to the first channel 120, and the other end is connected to the outlet 150. The water outlet device also includes a first valve 900, which includes a first valve core 910. The first valve core 910 is disposed at the connection between the third channel 180 and the first channel 120. The first valve core 910 can be driven to move to open or close the first channel 120. When the first channel 120 is open, water can flow from the first channel 120 to the outlet 150, and the first turbine 423 is driven to rotate. When the first channel 120 is closed, water flows through the third channel 180 to the outlet 150. The first turbine 423 locks, stopping shower liquid from entering the first channel 120 to meet the user's need for clean water. Furthermore, the water flows through the third channel 180 to the outlet 150 to prevent the turbine 423 from creating resistance to the water flow when using clean water, thereby increasing the pressure of the water flowing out of the outlet 150. It should be noted that the first valve core 910 is a common water circuit switching valve core, which will not be described in detail here.

[0080] A shower device according to a third aspect embodiment of the present invention includes a water supply device, a shower head, and a water outlet device according to either the first aspect embodiment or the second aspect embodiment. The water supply device is connected to the water inlet 140 of the water outlet device, and the shower head is connected to the water outlet 150.

[0081] It should be noted that this embodiment uses the water outlet device of the first aspect embodiment or the water outlet device of the second aspect embodiment, and therefore has at least all the beneficial effects brought by the technical solutions of the first aspect embodiment or the second aspect embodiment, which will not be repeated here.

[0082] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
