Description

Technical Field

[0001] This utility model relates to the field of shower technology, and in particular to a bubble machine and a shower device. Background Technology

[0002] While most mainstream shower systems on the market offer basic cleaning functions, these basic features are no longer sufficient to meet the diverse needs of consumers as their demands for bathroom products continue to rise. To improve ease of use, some high-end shower systems are now equipped with automatic foaming systems, solving the problem of needing to separately store shower gel, shampoo, and other toiletries in traditional showering methods. This not only simplifies the showering process but also significantly saves valuable bathroom space. However, existing automatic foaming shower systems still have significant functional defects: First, these products generally lack independent water-stopping devices, requiring users to operate a mixing valve to control the water flow; second, with prolonged use, shampoo and shower gel may clog the pipes, and the controller cannot stop drawing toiletries based on the pipe pressure, thus failing to protect the pipes.

[0031] The beneficial effects of this utility model are:

[0032] 1. The present invention proposes a bubble machine, including a diversion body, a foaming body, a control unit and a power supply. The diversion chamber is provided with a movable diversion valve core and is connected to an inlet, a first outlet and a second outlet. By driving the diversion valve core, the inlet is connected to the first outlet or the second outlet and the inlet is opened and closed. The water stop function can be achieved by the diversion valve core, and the user does not need to operate the mixing valve.

[0033] 2. The bubble machine proposed in this utility model has a foaming body with a foaming cavity. A pressure sensor is installed in the foaming cavity. When the pressure detected by the pressure sensor is greater than a preset value, the control unit shuts off the air supply device and the liquid supply device to stop supplying air and liquid to the foaming cavity, so as to avoid excessive pressure in the foaming cavity and damage to the foaming body. This effectively protects the pipeline and foaming structure, extends the service life of the equipment and improves the user experience.

[0034] 3. The bubble machine proposed in this utility model has a foaming body connected to a diversion body, so that the foam outlet is connected to the diversion chamber. By adjusting the position of the diversion valve core, the second water outlet can dispense raw water or foaming water, reducing the number of outlets and simplifying the structure.

[0035] 4. The bubble machine proposed in this utility model includes a first liquid supply device and a second liquid supply device. The first liquid supply device and the second liquid supply device are respectively used to supply shampoo and shower gel. Users can choose to use shampoo or shower gel separately according to their needs, which improves the flexibility and personalized experience of bathing.

[0036] 5. The bubble machine proposed in this utility model has a mode switching knob in the control unit. The mode switching knob has a first position, a second position and a third position to realize the shampoo foaming mode, the shower gel foaming mode and the raw water mode respectively. Users can intuitively switch the desired mode through the knob, which is convenient and easy to identify.

[0037] 6. The bubble machine proposed in this utility model is further equipped with a speed adjustment knob in the control unit, which is used to adjust the liquid pumping speed of the first liquid pump or the second liquid pump, so that the user can flexibly adjust the liquid output of shampoo or shower gel according to the foaming needs, further optimize the fineness of the foam and the amount used, and improve the bathing comfort and energy saving of the product.

[0038] 7. The bubble machine proposed in this utility model includes a foaming chamber comprising a rotating chamber and a foaming main chamber connected sequentially along the foaming direction. The water inlet, air inlet, and liquid inlet are respectively connected to the rotating chamber through guide channels. Each guide channel is inclined in the same clockwise direction, so that the fluids in each guide channel converge in the rotating chamber to form a mixed flow rotating in the same clockwise direction, thereby enhancing the rotational kinetic energy of the fluid, promoting the full mixing of water, air, and liquid, forming fine and uniform foam, improving foaming efficiency and foam quality, ensuring stable and continuous foaming, and optimizing the user experience.

[0039] 8. The present invention proposes a bubble machine, wherein the flow channel includes a first flow guide wall and a second flow guide wall relative to the first flow guide wall. The second flow guide wall is provided with a flow guide arc surface at one end connected to the first flow guide wall, so that the fluid in the flow guide channel converges with the fluid in the adjacent flow guide channel in a tangential or nearly tangential form, thereby reducing turbulence and resistance when the fluids converge, improving mixing efficiency, and enabling water, gas and liquid to quickly form a stable vortex in the rotating chamber, further enhancing the uniformity and fineness of the foam.

[0040] 9. This utility model proposes a bubble machine with an annular baffle inside the rotating chamber. The annular baffle divides the rotating chamber into an inner rotating chamber and an outer rotating chamber located outside the inner rotating chamber. The annular baffle has several flow channels, and the inner rotating chamber is connected to the outer rotating chamber through the flow channels. This causes a shearing effect when the mixed fluid passes through the flow channels, further breaking up the bubbles and refining the foam particles, thus improving the uniformity and density of the foam. At the same time, the annular baffle guides the fluid to flow in a spiral motion, extending the mixing path and enhancing the fusion effect of the water, gas, and liquid phases, ensuring a stable and continuous output of foam.

[0041] 10. The present invention proposes a bubble machine in which a plurality of porous foaming bodies are arranged at intervals along the foaming direction in the foaming chamber. The porous foaming bodies perform multiple refinement and homogenization processes on the foam in stages, making the foam denser and smoother and with a better feel. Attached Figure Description

[0058] The following is combined Figures 1-14 This utility model will be described in detail.

[0059] A bubble machine 10 includes a flow distribution body 20, a foaming body 40, and a control unit 100, etc. Specifically,

[0060] The diversion body 20 is provided with a diversion cavity 201 and an inlet 202, a first outlet 203, and a second outlet 204 connected to the diversion cavity 201. A movable diversion valve core 30 is provided within the diversion cavity 201. During its movement, the diversion valve core 30 has a first conducting position connecting the inlet 202 and the first outlet 203, a second conducting position connecting the inlet 202 and the second outlet 204, and a water-stopping position closing the inlet 202. In this embodiment, the diversion valve core 30 is axially movable along the diversion cavity 201, thereby enabling the inlet 202 to connect to either the first outlet 203 or the second outlet 204. In other embodiments, the diversion valve core 30 can also be rotatably connected to the diversion cavity 201, allowing the inlet 202 to connect to either the first outlet 203 or the second outlet 204 by rotating the diversion valve core 30.

[0061] The foaming body 40 is provided with a foaming chamber 401 and a water inlet 801, a foam outlet 802, an air inlet 803 and a liquid inlet 804 connected to the foaming chamber 401. The water inlet 801 is connected to the first water outlet 203. The air inlet 803 is connected to an air supply device. The liquid inlet 804 is connected to a liquid supply device. When the diversion valve core 30 is in the first conducting position, the foam outlet 802 discharges foaming water.

[0062] In this embodiment, a pressure sensor 90 is provided inside the foaming chamber 401. The bubble machine 10 also includes a control unit 100, which is electrically connected to the pressure sensor 90 and the power supply 120; when the pressure detected by the pressure sensor 90 is greater than a preset value, the control unit 100 shuts off the air supply device and the liquid supply device. The control unit 100 uses a PLA, PLC or microcontroller to implement logic control.

[0063] Compared to existing shower devices 200 with automatic foam dispensing, the bubble machine 10 proposed in this embodiment switches the water flow path by moving the diversion valve core 30, so that the inlet 202 is connected to the first outlet 203 or the second outlet 204 and the inlet 202 can be opened and closed. The user can realize the water stop function of the bubble machine 10 through the diversion valve core 30 without closing the mixing valve 210, simplifying the operation process. At the same time, when the pressure detected by the pressure sensor 90 is greater than the preset value, the control unit 100 shuts off the air supply device and the liquid supply device to stop the supply of air and liquid to the foaming chamber 401, so as to avoid excessive pressure in the foaming chamber 401 and damage to the foaming body 40. This effectively protects the pipeline and foaming structure, extends the service life of the equipment and improves the user experience.

[0064] like Figure 13 The diagram shows the logic of the bubble machine 10. The bubble outlet 802 of the foaming body 40 and the second water outlet 204 of the diversion body 20 converge at the confluence section, which is connected to the water outlet 220 via the outlet. The actual structure in use is as follows... Figure 5 As shown, the foaming body 40 is connected to the diversion body 20, so that the foam outlet 802 is connected to the diversion chamber 201. The foam outlet 802 is connected to the water outlet 202 through the second water outlet 204. A portion of the diversion chamber 201 forms a confluence section, and the second water outlet 204 forms a flow outlet. Specifically, when the diversion valve core 30 is in the first open position, the second water outlet 204 discharges foamed water; when the diversion valve core 30 is in the second open position, the second water outlet 204 discharges raw water. The advantage of this design is that the second water outlet 204 can discharge either raw water or foamed water, reducing the number of outlets and simplifying the structure.

[0065] like Figure 6As shown, the diversion valve core 30 is provided with a flow cavity 3011 and a first flow port 3012, a second flow port 3013, and a third flow port 3014 communicating with the flow cavity 3011. Further, the diversion valve core 30 includes a valve core body 301 and a connector 302 connected to the valve core body 301. The valve core body 301 is located within the diversion cavity 201 and is provided with the first flow port 3012, the second flow port 3013, and the third flow port 3014. The connector 302 is movably inserted through the diversion body 20, and one end of the connector 302 away from the valve core body 301 is connected to a button cap 303. The button cap 303 is configured as follows: Figure 13 The diversion switch button shown is used by the user to move the diversion valve core 30 via the button cap 303 to open and close the first flow port 3012, the second flow port 3013, and the third flow port 3014, as detailed below:

[0066] like Figure 7 As shown, when the diversion valve core 30 is in the first conducting position, the inlet 202, the first flow port 3012, the flow chamber 3011, the second flow port 3013 and the inlet 801 are connected in sequence, and the third flow port 3014 is in the closed state.

[0067] like Figure 8 As shown, when the diversion valve core 30 is in the second conducting position, the inlet 202, the first flow port 3012, the flow chamber 3011, the third flow port 3014 and the diversion chamber 201 are connected in sequence, and the second flow port 3013 is in the closed state.

[0068] like Figure 9 As shown, when the diversion valve core 30 is in the water-stop position, the first overflow port 3012 is not connected to the inlet port 202.

[0069] In this embodiment, a one-way valve 130 that opens in one direction along the foaming direction is provided between the foam outlet 802 and the diversion body 20 to prevent liquid in the foaming chamber 401 from flowing back into the foaming chamber 401, ensuring a stable and reliable foaming process and improving the uniformity and continuity of foaming.

[0070] like Figure 12As shown, the air supply device includes an air pump 140, the air inlet of which is connected to the atmospheric environment, and the air outlet of which is connected to the foaming chamber 401; the liquid supply device includes a first liquid supply device 150 and a second liquid supply device 160, which are respectively used to supply shampoo and shower gel. The first liquid supply device 150 includes a first liquid storage bottle 1501 and a first liquid pump 1502 that are connected to each other. The second liquid supply device 160 includes a second liquid storage bottle 1601 and a second liquid pump 1602 that are connected to each other. The liquid outlets of the first liquid pump 1502 and the second liquid pump 1602 are respectively connected to the foaming chamber 401. The control unit 100 is electrically connected to the air pump 140, the first liquid pump 1502 and the second liquid pump 1602.

[0071] like Figure 1 , Figure 2 , Figure 3 as well as Figure 12 As shown, the control unit 100 is equipped with a mode switching knob 1101 and a speed adjustment knob 1102, used to control the combined operating mode of the first liquid pump 1502, the second liquid pump 1602, and the air pump 140, as well as the pumping speed of the first liquid pump 1502 and the second liquid pump 1602. Specifically:

[0072] The mode switching knob 1101 has three positions: a first position, a second position, and a third position, to respectively achieve shampoo foaming mode, shower gel foaming mode, and undiluted water mode. Users can intuitively switch between the desired modes using the knob, making operation convenient and easy to identify. Furthermore, when the mode switching knob 1101 is in the first position, the first liquid pump 1502 and the air pump 140 are activated, which is the shampoo foaming mode, and the second outlet 204 discharges the shampoo foaming liquid. When the mode switching knob 1101 is in the second position, the second liquid pump 1602 and the air pump 140 are activated, which is the shower gel foaming mode, and the second outlet 204 discharges the shower gel foaming liquid. When the mode switching knob 1101 is in the third position, the air pump 140 is activated, which is the undiluted water mode. Shampoo and shower gel are no longer supplied to the foaming chamber 401; the undiluted water and air clean the foaming chamber 401, expelling any remaining shampoo or shower gel.

[0073] When the mode switching knob 1101 is in the first position, the speed control knob 1102 is used to adjust the pumping speed of the first liquid pump 1502; when the mode switching knob 1101 is in the second position, the speed control knob 1102 is used to adjust the pumping speed of the second liquid pump 1602. Users can flexibly adjust the amount of shampoo or shower gel dispensed according to their foaming needs, further optimizing the fineness of the foam and the amount used, improving bathing comfort and product energy efficiency.

[0074] like Figure 10 and Figure 11As shown, the foaming chamber 401 includes a rotating chamber 4011 and a foaming chamber 4012 connected sequentially along the foaming direction. The water inlet 801, air inlet 803 and liquid inlet 804 are connected to the rotating chamber 4011 through the flow guide channel 60. The sensing end of the pressure sensor 90 is located in the rotating chamber 4011, and the foam outlet 802 is connected to the foaming chamber 4012.

[0075] like Figure 11 As shown, each flow channel 60 is inclined in the same clockwise direction, so that the fluid in each flow channel 60 converges in the rotating cavity 4011 to form a mixed flow that rotates in the same clockwise direction. This enhances the rotational kinetic energy of the fluid, promotes the full mixing of water, gas and liquid, forms fine and uniform foam, improves foaming efficiency and foam quality, ensures stable and continuous foaming, and optimizes the user experience.

[0076] The flow channel 60 includes a first flow guide wall 601 and a second flow guide wall 602 relative to the first flow guide wall 601. The flow guide length of the first flow guide wall 601 is less than the flow guide length of the second flow guide wall 602. The first flow guide wall 601 and the second flow guide wall 602 are respectively connected to the second flow guide wall 602 and the first flow guide wall 601 in adjacent flow channels 60 on both sides. The end of the second flow guide wall 602 connected to the first flow guide wall 601 is provided with a flow guide arc surface 6021, so that the fluid in the flow channel 60 converges with the fluid in the adjacent flow channel 60 in a tangential or nearly tangential form, reducing turbulence and resistance when the fluid converges, improving mixing efficiency, and enabling water, gas and liquid to quickly form a stable vortex in the rotating cavity 4011, further enhancing the uniformity and fineness of the foam.

[0077] like Figure 11 As shown, an annular baffle 50 is provided inside the rotating cavity 4011, dividing the rotating cavity 4011 into an inner rotating cavity 40111 and an outer rotating cavity 40112 located outside the inner rotating cavity 40111. The annular baffle 50 is provided with several flow channels 501. The inner rotating cavity 40111 is connected to the outer rotating cavity 40112 through the flow channels 501. Each guide channel 60 is connected to the outer rotating cavity 40112, and the inner rotating cavity 40111 is connected to the foaming cavity 4012. When the mixed fluid passes through the flow channels 501, a shearing effect is generated, further breaking up the bubbles and refining the foam particles, improving the uniformity and density of the foam. At the same time, the annular baffle 50 guides the fluid to flow in a spiral, extending the mixing path, enhancing the fusion effect of the water, gas, and liquid phases, and ensuring stable and continuous foam output.

[0078] like Figure 5 and Figures 7 to 9As shown, a number of porous foaming bodies 70 are spaced apart in the foaming cavity 4012 along the foaming direction. Specifically, there are two porous foaming bodies 70, which are respectively set at the front end and the rear end of the foaming cavity 4012. They are stacked one after the other to refine the foam step by step. The front-stage porous foaming body 70 achieves preliminary gas-liquid homogenization, and the rear-stage porous foaming body 70 further compacts and homogenizes the foam, so that the final foam is delicate, dense and stable, effectively reducing liquid residue and waste.

[0079] like Figure 12 and Figure 13 As shown, the diversion body 20 is equipped with a position sensor 170 for detecting the position of the diversion valve core 30. The position sensor 170 is electrically connected to the control unit 100. When the position sensor 170 detects that the diversion valve core 30 is in the first conducting position, foaming water is discharged from the second outlet 204. The control unit 100 controls the air supply device and the liquid supply device to work, and the power supply 120 supplies power to the control unit 100 so that the control unit 100 can receive the pressure value monitored by the pressure sensor 90. When the position sensor 170 detects that the diversion valve core 30 is in other positions, the control unit 100 controls the air supply device and the liquid supply device to stop working, and the power supply 120 stops supplying power. Furthermore, the position sensor 170 is a position switch. When the diversion valve core 30 is in the first conducting position, the position switch is triggered, the control unit 100 is energized and starts working; when the diversion valve core 30 is in the second conducting position or the water-stopping position, the position switch is not triggered, the control unit 100 is de-energized and stops working, thereby realizing on-demand power supply. The advantage of this design is that the power supply 120 only supplies power to the control unit 100 in the foaming state, thereby effectively reducing standby power consumption and extending the service life of the power supply 120.

[0080] The bubble machine 10 proposed in this embodiment further includes an inner shell 180 for fixing the flow distribution body 20, the foaming body 40, the control unit 100, and the power supply 120.
