Description

Technical Field

[0001] This invention relates to the field of bathroom products, specifically to a water outlet device and a shower equipment. Background Technology

[0002] Shampoo or shower gel requires manual lathering before application. While existing shower equipment allows shampoo or shower gel to be added directly to the showerhead and mixed with water before being sprayed out for easy application, the lathering effect of this type of shower equipment is poor, with barely any visible bubbles. Users still need to lather the water before application, which is inconvenient. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a water outlet device and shower equipment that can spray out foam water with obvious foaming effect, so that users can apply it directly without manually rubbing to create foam.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The first technical solution relates to a water outlet device, comprising: a body having an inlet, an outlet, and a first water passage connecting the inlet and the outlet; a first switching valve disposed within the first water passage for opening and closing the first water passage; a liquid storage unit for containing a functional liquid; and a foaming unit having an inlet and an outlet, the inlet connecting the liquid storage unit, and the outlet located between the first switching valve and the outlet; when the foaming unit is in operation, it draws in the functional liquid, foams it, and outputs it to the first water passage through the outlet.

[0006] The second technical solution is based on the first technical solution, and further includes a sensing component (11) which has a pressure-bearing part and a triggering part. The pressure-bearing part is located between the first switching valve (6) and the water outlet (4), and is adapted to be displaced to a first position under water pressure when water flows through the first water passage (5). The triggering part is triggered when the pressure-bearing part is displaced to the first position to control the foaming unit (8) to enter the working state. The "control" in this technical solution should be interpreted as having a logical causal relationship, that is, when the triggering part is triggered, the foaming unit enters the working state accordingly.

[0007] The third technical solution is based on the second technical solution, wherein the sensing component (11) is further provided with an elastic part, the elastic part is adapted to deform when the pressure bearing part is displaced to the first position and to recover the deformation when the first water passage (5) is not filled with water, so that the pressure bearing part is displaced away from the first position; the triggering part also controls the foaming unit (8) to exit the working state when the pressure bearing part is displaced away from the first position.

[0008] The fourth technical solution is based on the third technical solution, wherein the sensing component (11) includes a sliding member (12), an elastic member (13), and a trigger member (14); the sliding member (12) forms the pressure-bearing part, which is slidably mounted on the body (2) along the first direction, and the pressure-bearing part on it is adapted to be driven by water pressure to move the sliding member (12) to a first position; the elastic member (13) forms the elastic part, and its two ends abut against the sliding member (12) and the body (2) respectively along the first direction; the trigger member (14) forms the trigger part, and it is adapted to be triggered by the sliding member (12).

[0009] The fifth technical solution is based on any one of the first to fourth technical solutions, wherein the main body (2) is further provided with a second water passage (15) connecting the water inlet (3) and the water outlet (4); the water outlet device (1) further includes a second switch valve (16) for opening and closing the second water passage (15).

[0010] The sixth technical solution is based on the fifth technical solution, wherein the main body (2) is further provided with a second water passage (15) connecting the water inlet (3) and the water outlet (4); the water outlet device (1) further includes a second switch valve (16), which is used to open and close the second water passage (15).

[0011] The seventh technical solution is based on the sixth technical solution, wherein the foaming unit (8) is a diaphragm pump.

[0012] The eighth technical solution is based on the seventh technical solution, and further includes an interaction unit (18) and a control unit (19). The interaction unit (18) is used to receive foaming instructions, water outlet instructions and water shut-off instructions, and sends a foaming signal to the control unit (19) when receiving the foaming instruction, sends a water outlet signal to the control unit (19) when receiving the water outlet instruction, and sends a water shut-off signal to the control unit (19) when receiving the water shut-off instruction. The control unit (19) is used to receive the foaming signal, the water outlet signal and the water shut-off signal, and opens the first switch valve (6) and closes the second switch valve (16) when receiving the foaming signal, closes the first switch valve (6) and opens the second switch valve (16) when receiving the water outlet signal, and closes the first switch valve (6) and the second switch valve (16) when receiving the water shut-off signal.

[0013] The ninth technical solution is based on the eighth technical solution, and further includes a power supply unit (20) for supplying power to the foaming unit (8), the sensing component (11), the interaction unit (18) and the control unit (19).

[0014] The tenth technical solution relates to a shower device, which includes a shower head (22), a shower spray head (24) and a water outlet device (1) as described in any one of the first to ninth technical solutions, wherein the water outlet end (23) of the shower head (22) is connected to the water inlet (3) and the water inlet end (25) of the shower spray head (24) is connected to the water outlet (4).

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] In the first technical solution, the foaming unit foams the functional liquid in the storage unit before outputting it to the first water channel. This allows the foamed functional liquid to mix with water and then be sprayed out through the outlet. Therefore, users can directly obtain a foaming solution with a noticeable lather, without the need for manual lathering before application. In practical applications, users can add a mixture of water and shower gel to the storage unit to achieve a better foaming effect, and then connect the outlet to the shower head's inlet so that the foaming solution can be sprayed out for application. Furthermore, because the functional liquid is foamed before being mixed with water and then sprayed through the shower head, compared to methods that spray directly without mixing with water after foaming, there is no problem of difficulty in spraying due to poor fluidity, and it provides users with a completely new showering experience.

[0017] In the second technical solution, the pressure-bearing part only moves to the first position to trigger the triggering part and control the foaming unit when water flows through the first water passage. However, if the foaming unit is directly activated by opening the water outlet device, it will still enter the working state when the water supply is stopped, causing the foamed functional liquid to enter the first water passage. This not only wastes the functional liquid but also, since the first switch valve is open at this time, the foamed functional liquid will flow out from the inlet, thus contaminating the water system. Therefore, compared to directly activating the foaming unit by opening the water outlet device, the water outlet device of this technical solution can avoid the waste of functional liquid and the contamination of the water system when the water supply is stopped.

[0018] In the third technical solution, by adding an elastic part, the pressure-bearing part can automatically move away from the first position when the first water passage is not filled with water, thereby causing the foaming unit to exit the working state, avoiding the waste of power consumption caused by the foaming unit continuing to work after the water outlet device is turned off.

[0019] In the fourth technical solution, the pressure-bearing part, elastic part, and triggering part are formed by using sliding parts, elastic parts, and triggering parts respectively, which facilitates assembly and installation.

[0020] In the fifth technical solution, by adding a second switch valve and a second water passage in the main body, the user can use the water outlet device to use raw water even when not using bubble water, thus meeting the user's need for raw water.

[0021] In the sixth technical solution, since the water outlet can be connected to external devices such as shower heads, and shower heads are generally located at a high position, they will form a communicating vessel when the water is closed, causing water to flow back into the foaming unit. Therefore, by setting a check valve between the liquid outlet and the water outlet, water can be prevented from flowing back into the foaming unit from the water outlet and thus contaminating the functional liquid.

[0022] In the seventh technical solution, since the foaming unit uses a diaphragm pump, it not only has a large foaming volume and high foaming efficiency, but also has a certain squeezing capacity, which can squeeze the poorly flowing functional liquid after foaming into the first water passage.

[0023] In the eighth technical solution, by setting up an interactive unit and a control unit, the operation of the water outlet device is integrated into foaming command, water outlet command and water shut-off command, which is convenient for users to operate.

[0024] In the ninth technical solution, a power supply unit is set up to supply power to the foaming unit, sensing components, interaction unit and control unit, which allows the water outlet device to be used directly without an external power supply, which is more convenient.

[0025] In the tenth technical solution, the water outlet device provided by any of the first to ninth technical solutions is adopted, thus achieving the corresponding effect. Attached Figure Description

[0039] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0040] This embodiment provides a water dispensing device 1, which can not only dispense bubble water but also dispense raw water. For example... Figure 1 As shown, the water outlet device 1 includes a body 2, a first switching valve 6, a second switching valve 16, a liquid storage unit 7, a foaming unit 8, a sensing component 11, a check valve 17, an interaction unit 18, a control unit 19, and a power supply unit 20.

[0041] The main body 2 is provided with an inlet 3, an outlet 4, and a first water passage 5 and a second water passage 15 connecting the inlet 3 and the outlet 4.

[0042] The first switching valve 6 is disposed within the first water passage 5 and is used to open and close the first water passage 5. In this embodiment, the first switching valve 6 is a solenoid valve.

[0043] The second switching valve 16 is used to open and close the second water passage 15. In this embodiment, the second switching valve 16 is a solenoid valve and is disposed within the second water passage 15.

[0044] The liquid storage unit 7 is used to hold the functional liquid. When the water outlet device 1 is used for bathing, after filling the liquid storage unit 7 with shampoo or shower gel, an appropriate amount of water can be added to obtain a better foaming effect.

[0045] The foaming unit 8 has an inlet 9 and an outlet 10. The inlet 9 is connected to the storage unit 7, and the outlet 10 is located between the first switch valve 6 and the water outlet 4. When the foaming unit 8 is in operation, it draws functional liquid from the storage unit 7, foams it, and then outputs it to the first water passage 5 through the outlet 10. In this embodiment, a diaphragm pump is used as the foaming unit 8.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the sensing component 11 has a pressure-bearing part, an elastic part, and a triggering part. The pressure-bearing part is located between the first switch valve 6 and the outlet 4. It is adapted to be displaced to a first position by water pressure when water flows through the first water passage 5, causing the elastic part to deform. When the first water passage 5 is not filled with water, it is displaced away from the first position by the elastic part. The triggering part is triggered when the pressure-bearing part is displaced to the first position to control the foaming unit 8 to enter the working state, and to control the foaming unit 8 to exit the working state when the pressure-bearing part is displaced away from the first position. Specifically, the sensing component 11 includes a sliding member 12, an elastic member 13, and a triggering member 14, which respectively form the pressure-bearing part, the elastic part, and the triggering part. The sliding member 12 is slidably mounted on the body 2 along a first direction. The pressure-bearing part on it is adapted to be driven by water pressure to displace the sliding member 12 to the first position. The two ends of the elastic member 13 abut against the sliding member 12 and the body 2 respectively along the first direction. The triggering member 14 is adapted to be triggered by the sliding member 12. In this embodiment, the triggering member 14 is disposed in the sliding direction of the sliding member 12. Furthermore, since the trigger 14 in this embodiment uses a Hall sensor, the slider 12 can be triggered without direct contact. It should be clarified that the trigger 14 does not necessarily need to be a Hall sensor; any sensor capable of detecting the displacement of the pressure-bearing part to the first position is sufficient, such as a point-contact sensor. In addition, the arrangement of the pressure-bearing part and the elastic part is not limited to the arrangement provided in this embodiment. As long as the pressure-bearing part can displace under water pressure and deform the elastic part, and then return to its original position due to the action of the elastic part when the water pressure is low or non-existent, it is acceptable. For example, the pressure-bearing part can be formed on a thin sheet with one end hinged to the inner wall of the first water passage 5 and the other end inclined towards the water outlet direction, while the two ends of the elastic part act on the thin sheet and the body 2 respectively. Therefore, the thin sheet can continue to tilt towards the inner wall under water pressure, causing the elastic part to deform, and then return to its original position due to the action of the elastic part when there is no water pressure or the water pressure is low. In this embodiment, the sensing component 11 directly interacts with the foaming unit 8. Of course, it can also be uniformly controlled by the control unit 19. That is, after the triggering part of the sensing component 11 is triggered, it sends a signal to the control unit 19, and the control unit 19 then controls the foaming unit 8 to enter the working state.

[0047] like Figure 1As shown, the check valve 17 is located between the liquid outlet 10 and the water outlet 4 to prevent water from flowing back from the water outlet 4 to the liquid outlet 10. Since the check valve 17 is existing technology, it will not be described in detail here.

[0048] like Figure 1 , Figure 3 and Figure 6 As shown, the interaction unit 18 is used to receive foaming commands, water dispensing commands, and water shut-off commands. Upon receiving a foaming command, it sends a foaming signal to the control unit 19; upon receiving a water dispensing command, it sends a water dispensing signal to the control unit 19; and upon receiving a water shut-off command, it sends a water shut-off signal to the control unit 19. The interaction unit 18 can be a touch-sensitive panel or a knob; these are existing technologies and will not be described further.

[0049] The control unit 19 is used to receive a foaming signal, a water outlet signal, and a water shut-off signal, and to open the first switch valve 6 and close the second switch valve 16 when the foaming signal is received, to close the first switch valve 6 and open the second switch valve 16 when the water outlet signal is received, and to close the first switch valve 6 and the second switch valve 16 when the water shut-off signal is received.

[0050] like Figure 1 and 3 As shown, the power supply unit 20 supplies power to the foaming unit 8, the sensing component 11, the interaction unit 18, and the control unit 19. In other embodiments, an external power supply can also be used to power the water outlet device 1.

[0051] When in use, when the user inputs a water dispensing command, such as... Figure 4 As shown, at this time, the first switch valve 6 is closed and the second switch valve 16 is open, allowing the user to directly use the raw water. When the user inputs a foaming command, as shown... Figure 5 As shown, at this time, the first switch valve 6 is open and the second switch valve 16 is closed. The pressure-bearing part, under the action of water pressure, shifts to the first position, thereby triggering the foaming unit 8 to enter the working state. The foaming unit 8 draws functional liquid from the storage unit 7, foams it, and then outputs it to the first water passage 5 to mix with water before being output through the outlet 4. When the user inputs a water shut-off command, such as... Figure 1 As shown, at this time, both the first switch valve 6 and the second switch valve 16 are closed, thereby shutting off the water outlet, while the pressure-bearing part leaves the first position under the action of the elastic part, thereby causing the trigger part to control the foaming unit 8 to exit the working state.

[0052] This embodiment also provides a shower device 21, which has the same function as the water outlet device 1 in this embodiment, such as... Figure 6As shown, it includes a shower head 22, a shower 24, and a water outlet device 1 provided in this embodiment. The water outlet 23 of the shower head 22 is connected to the water inlet 3 of the water outlet device 1, and the water inlet 25 of the shower head 24 is connected to the water outlet 4 of the water outlet device 1. Since the shower head 22 and the shower 24 are both existing technologies, they will not be described in detail here.

[0053] In this embodiment, the foaming unit 8 foams the functional liquid in the storage unit 7 before outputting it to the first water passage 5. This allows the foamed functional liquid to mix with water and then be sprayed out through the water outlet 4. Therefore, the user can directly obtain foamy water with a noticeable foaming effect, without the need for manual lathering before application. Furthermore, since the functional liquid is foamed before being mixed with water and then sprayed out through the shower head 24, compared to methods that spray directly without mixing with water after foaming, there is no problem of difficulty in spraying due to poor fluidity, and it provides the user with a completely new showering experience.

[0054] In this embodiment, the pressure-bearing part only moves to the first position to trigger the triggering part when water flows through the first water passage 5, thereby controlling the operation of the foaming unit 8. However, if the foaming unit 8 is directly activated by opening the water outlet device 1, the foaming unit 8 will still enter the working state when the water supply is stopped, causing the foamed functional liquid to enter the first water passage 5. This not only wastes the functional liquid, but also, since the first switch valve 6 is in the open state at this time, the foamed functional liquid will flow out from the water inlet 3, thus contaminating the water circuit. Therefore, compared with directly activating the foaming unit 8 by opening the water outlet device 1, the water outlet device 1 using this technical solution can not only avoid the waste of functional liquid when the water supply is on but also prevent the functional liquid from contaminating the water circuit.

[0055] In this embodiment, by adding an elastic part, the pressure-bearing part can automatically move away from the first position when the first water passage 5 is not filled with water, thereby causing the foaming unit 8 to exit the working state, avoiding the waste of power consumption caused by the foaming unit 8 continuing to work after the water outlet device 1 is turned off.

[0056] In this embodiment, the sliding member 12, the elastic member 13, and the trigger member 14 are used to form the pressure-bearing part, the elastic part, and the triggering part, respectively, which facilitates assembly and installation.

[0057] In this embodiment, by adding a second switch valve 16 and a second water passage 15 in the main body 2, the user can use the water outlet device 1 to use raw water even when not using bubble water, thus meeting the user's need for raw water.

[0058] In this embodiment, since the water outlet 4 can be connected to devices such as the shower head 24, and the shower head 24 is generally located at a high position, it will form a communication channel when the water is closed, causing water to flow back into the foaming unit 8. Therefore, by setting a check valve 17 between the liquid outlet 10 and the water outlet 4, water can be prevented from flowing back from the water outlet 4 into the foaming unit 8 and thus contaminating the functional liquid.

[0059] In this embodiment, since the foaming unit 8 uses a diaphragm pump, it not only has a large foaming volume and high foaming efficiency, but also has a certain squeezing capacity, which can squeeze the foamed functional liquid with poor flowability into the first water passage 5.

[0060] In this embodiment, by setting up an interaction unit 18 and a control unit 19, the operation of the water outlet device 1 is integrated into foaming command, water outlet command and water shut-off command, which is convenient for users to operate.

[0061] In this embodiment, the foaming unit 8, sensing component 11, interaction unit 18 and control unit 19 are powered by a power supply unit 20, which allows the water outlet device 1 to be used directly without an external power supply, which is more convenient.

[0062] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
