Description

Technical Field

[0001] This article relates to the field of bathroom technology, and in particular to a driving module, a scrubbing and foaming component, and a water outlet device. Background Art

[0002] In the prior art, there are water outlet devices that can simultaneously meet the needs of massage and foaming. When consumers take a bath or scrub their bodies, they can install a massage head on the water outlet device and scrub the body by rotating the massage head. To avoid damaging the skin, the output speed of the massage head is relatively low. When foaming is needed, the massage head needs to be removed and replaced with a foaming component, which has the functions of foaming and brushing.

[0003] However, since the output speed of the massage head is very low, after replacing the foaming component, the low speed operation of the foaming component is not enough to allow the shower gel to produce rich and delicate foam, so it cannot meet the consumer's needs for scrubbing and foaming while taking a bath.

[0029] The embodiment of the present application provides a driving module 100, such as Figure 1-Figure 8 As shown, it includes: a driving motor 102, a first output shaft 103 and a second output shaft 104, one of the first output shaft 103 and the second output shaft 104 is sleeved outside the other, and the rotation axes of the first output shaft 103 and the second output shaft 104 are located on the same straight line.

[0030] A transmission mechanism is provided between at least one of the first output shaft 103 and the second output shaft 104 and the drive shaft of the drive motor 102 , and the transmission mechanism is configured to make the rotation speeds of the first output shaft 103 and the second output shaft 104 different.

[0031] The driving module 100 provided in the embodiment of the present application has two output shafts with different speeds, so that the driving module 100 can be connected to two devices with different speed requirements. For example, the first output shaft 103 of the driving module 100 can be connected to the scrubbing module 200 with a low speed requirement, and the second output shaft 104 can be connected to the foaming module 300 with a high speed requirement. Because the scrubbing module 200 is used for scrubbing when taking a bath, the speed should be low to avoid damage to the skin, and the foaming module 300 needs to make foam for the bath gel, which requires a faster speed. When the driving module 100 is connected to the scrubbing module 200, automatic scrubbing can be achieved, and when the foaming module 300 is connected, automatic foaming can be achieved, eliminating the time of applying the shower gel by oneself, saving bathing time, and improving bathing efficiency. Therefore, the solution provided by the present application can use the driving module to cooperate with the scrubbing module and the foaming module to automatically scrub and foam when taking a bath, meet the needs of consumers for scrubbing and foaming when taking a bath, and improve bathing efficiency. The driving module 100 can be used alone in conjunction with the scrubbing module 200 and the foaming module 300, or can be installed on a water outlet device such as a shower head and used in conjunction with the scrubbing module 200 and the foaming module 300.

[0032] In one embodiment, a first transmission mechanism is provided between the driving shaft of the driving motor 102 and the first output shaft 103 , and a second transmission mechanism is provided between the driving shaft of the driving motor 102 and the second output shaft 104 .

[0033] like Figure 2 As shown, the first output shaft 103 is sleeved on the outside of the second output shaft 104, a first gear 1031 is provided at one end of the first output shaft 103, and a second gear 1041 is provided at one end of the second output shaft 104 extending out of the first output shaft 103. The first transmission mechanism includes a driving gear 1021 provided on the driving shaft and a first gear 1031 drivingly connected to the driving gear 1021; the second transmission mechanism includes a driving gear 1021 provided on the driving shaft and a second gear 1041 drivingly connected to the driving gear 1021.

[0034] exist Figure 2 In the embodiment, the rotation speed of the first output shaft 103 is less than the rotation speed of the second output shaft 104 , and the reduction ratio of the first transmission mechanism can be set to be greater than the reduction ratio of the second transmission mechanism, so that the rotation speed of the first output shaft 103 is less than the rotation speed of the second output shaft 104 .

[0035] To make the rotation speed of the first output shaft 103 lower than that of the second output shaft 104 , the number of teeth of the first gear 1031 can be set to be greater than that of the second gear 1041 . The greater number of teeth of the first gear 1031 than that of the second gear 1041 can also facilitate the spatial arrangement of the gears.

[0036] Figure 7The structure of a first output shaft 103 with a first gear 1031 in one embodiment is shown. One end of the first output shaft 103 is connected to the first gear 1031, and the other end is provided with a first connector 1032. The first connector 1032 is used to cooperate with a device with a low rotation speed during operation, such as connecting to the scrubbing module 200. Figure 8 The structure of the second output shaft 104 in an embodiment is shown, one end of the second output shaft 104 is provided with an anti-rotation structure 1042, the anti-rotation structure 1042 is provided with a second gear 1041, so that the second gear 1041 can drive the second output shaft 104 to rotate together, and the other end of the second output shaft 104 is provided with a second connector 1044, and the second connector 1044 is used to cooperate with a device with a high rotation speed during operation, such as connecting the frothing module 300. Figure 7 The first output shaft 103 shown can be sleeved on Figure 8 The outer side of the second output shaft 104 is shown as Figure 2 Status shown.

[0037] In one embodiment, the first transmission mechanism further includes a first transmission gear set disposed between the driving gear 1021 and the first gear 1031 ; the second transmission mechanism further includes a second transmission gear set disposed between the driving gear 1021 and the second gear 1041 .

[0038] like Figure 2-Figure 6 In the example shown, the first transmission gear set arranged between the driving gear 1021 and the first gear 1031 includes a first intermediate gear 105, a second intermediate gear 106 and a third intermediate gear 107; the first intermediate gear 105 includes a first intermediate large gear 1051 and a first intermediate small gear 1052 having a smaller number of teeth than the first intermediate large gear 1051, and the first intermediate large gear 1051 and the first intermediate small gear 1052 are coaxially fixed; the second intermediate gear 106 includes a second intermediate large gear 1061 and a second intermediate small gear 1062 having a smaller number of teeth than the second intermediate large gear 106, and the second intermediate large gear 1061 and the second intermediate small gear 1062 are coaxially fixed; the third intermediate gear 107 includes a third intermediate large gear 1071 and a third intermediate small gear 1072 having a smaller number of teeth than the third intermediate large gear 1071, and the third intermediate large gear 1071 and the third intermediate small gear 1072 are coaxially fixed.

[0039] The first intermediate large gear 1051 meshes with the driving gear 1021, the first intermediate small gear 1052 meshes with the second intermediate large gear 10611, the second intermediate small gear 1062 meshes with the third intermediate large gear 1071, and the third intermediate small gear 1072 meshes with the first gear 1031. That is, a multi-stage reduction is set between the driving gear 1021 and the first gear 1031.

[0040] In one example, the second transmission gear set arranged between the driving gear 1021 and the second gear 1041 includes a first intermediate large gear 1051, a first intermediate small gear 1052 and a second intermediate large gear 1061, the first intermediate large gear 1051 is meshed with the driving gear 1021, the first intermediate small gear 1052 is meshed with the second intermediate large gear 1061, and the second intermediate large gear 1061 is meshed with the second gear 1041.

[0041] Those skilled in the art will appreciate that the first transmission mechanism and the second transmission mechanism may have a variety of transmission modes and are not limited to the above-mentioned gear arrangement mode. Fewer reduction gears or more reduction gears may be set according to the required rotational speed of each output shaft to change the reduction ratio, or the reduction ratio may be changed by changing the number of teeth on the gears.

[0042] It can also be understood that the driving shaft of the driving motor 102 can directly drive the first output shaft 103 or the second output shaft 104 , that is, a transmission mechanism is provided between one of the first output shaft 103 and the second output shaft 103 and the driving shaft of the driving motor 102 .

[0043] In the above embodiment, the first output shaft 103 with a low rotation speed is sleeved on the outside of the second output shaft 104. It is understandable that in other embodiments, the second output shaft 104 with a high rotation speed may also be sleeved on the outside of the first output shaft 103. It is sufficient to make an adaptive change to the gear assembly.

[0044] In one embodiment, Figure 1-Figure 3 As shown, the driving module 100 also includes a housing 101, the housing 101 includes a main housing 1011 with an open end and a cover 1012 covering the open end, the driving motor 102 and the transmission mechanism (a transmission mechanism between at least one of the first output shaft 103 and the second output shaft 104 and the driving shaft of the driving motor 102) are installed in the cavity between the main housing 1011 and the cover 1012, and the ends of the first output shaft 103 and the second output shaft 104 are extended from the cavity to the outside of the cover 1012. In addition, a battery can be arranged in the cavity in the housing 101, and a power button 1013 is arranged on the housing 101 (refer to Figure 1 ), by pressing the power button 1013, the driving module 100 can be controlled to start and shut down.

[0045] In one embodiment, the driving module 100 further includes a base 109 fixed to the inner side of the cover 1012, and the rotating shaft 108 of some gears in the transmission mechanism is installed on the base 109. Figure 3As shown, a plurality of positioning holes are provided on the base 109 , and the rotating shafts 108 of the first middle gear 105 , the second middle gear 106 and the third middle gear 107 can be respectively installed in the positioning holes of the base 109 .

[0046] In addition, since the driving module 100 can be used to drive the scrubbing module 200 and the foaming module 300 for use in bathing, the driving module 100 needs to be waterproof. Figure 2 As shown, a first sealing ring 110 is provided between the base 109 and the cover 1012. The first sealing ring 110 is provided around the first output shaft 103 and the second output shaft 104 to prevent water from entering the inner side of the driving module 100 from the gap between the base 109 and the first output shaft 103 or the second output shaft 104 sleeved on the outside. A second sealing ring 111 may be provided between the first output shaft 103 and the second output shaft 104 to prevent water from entering the inner side of the driving module 100 from the gap between the first output shaft 103 and the second output shaft 104. The second sealing ring 111 may be provided between the annular groove 1043 of the second output shaft 104 and the first output shaft 103 (refer to Figure 2 and Figure 8 ).

[0047] The embodiment of the present application also provides a scrubbing and foaming component, including a scrubbing module 200, a foaming module 300 and the driving module 100 as described above, wherein the scrubbing module 200 is configured to be detachably mounted on the first output shaft 103, and the foaming module 300 is configured to be detachably mounted on the second output shaft 104.

[0048] Fig. 9 and Fig.10 The scrubbing module 200 in one embodiment is shown. The scrubbing module 200 is provided with a first docking interface 201. Fig.11 The structure after the scrubbing module 200 is installed on the driving module 100 is shown, and the first docking interface 201 of the scrubbing module 200 is connected to the first connecting joint 1032 of the first output shaft 103. The first output shaft 103 has a first connecting joint 1032 with a polygonal outline (refer to Figure 7 ), the first docking interface 201 of the scrubbing module 200 is a polygonal interface that matches the polygonal outer contour, so that the first output shaft 103 drives the scrubbing module 200 to rotate.

[0049] Fig.12 and Fig.13The foaming module 300 in one embodiment is shown, and the foaming module 300 has a second docking port 3021, which is used to connect with the second connector 1044 of the second output shaft 104 of the driving module 100, so that the driving module 100 drives the foaming module 300 to foam. The second connector 1044 can be flat, and the second docking port 1032 is configured to cooperate with the flat structure of the second connector 1044. Fig.19 A schematic diagram of the structure in which a foaming module 300 is installed on a driving module 100 in one embodiment is shown.

[0050] In one embodiment, Fig.14 and Fig.15 As shown, the foaming module 300 includes a mounting shell 301 with a liquid injection port 3013, a foaming wheel 302 located in the mounting shell 301, a reduction mechanism connected to the foaming wheel 302, and a brush head 308 rotatably mounted on the mounting shell 301; wherein the liquid injection port 3013 can be blocked by a blocking cover 3014, and the foaming liquid injected into the mounting shell 301 from the liquid injection port 3013 is foamed under the stirring of the foaming wheel 302, and the foamed foam fluid can flow to the brush head 308, so that foam can be applied to the body through the brush head 308.

[0051] Among them, the foaming wheel 302 is configured to be connected to the second output shaft 104, so that the second output shaft 104 drives the foaming wheel 302 to rotate so that the foaming wheel 302 stirs the foaming liquid. When the foaming wheel 302 rotates, it drives the deceleration mechanism to drive the brush head 308 to rotate at a speed less than the rotation speed of the foaming wheel 302.

[0052] Since the foaming wheel 302 for foaming the foaming liquid (such as shower gel) needs to have a higher rotation speed to produce rich foam, and the brush head 308 for applying foam to the body cannot have a higher rotation speed to avoid hurting the body, a reduction mechanism is provided between the foaming wheel 302 and the brush head 308 so that the rotation speed of the brush head 308 is reduced by the reduction mechanism when the foaming wheel 302 drives the brush head 308 to rotate.

In this way, when the foaming wheel 302 rotates, the central gear 3023 drives the plurality of planetary gears 305 to rotate, and the rotation of the plurality of planetary gears 305 drives the ring gear 304 to rotate, and the planetary gear transmission mechanism can achieve speed reduction of the ring gear 304.

[0054] The gear ring 304 is arranged to be circumferentially limited with the brush head 308 so that the brush head 308 is driven to rotate by the gear ring 304. The foaming wheel 302 can make the rotation speed of the gear ring 304 lower than the rotation speed of the foaming wheel 302 through the reduction transmission between the central gear 3023, the planetary gear 305 and the gear ring 304, so that the rotation speed of the brush head 308 is lower than the rotation speed of the foaming wheel 302.

It can be understood that in order to make the gear ring 304 drive the brush head 308 to rotate, the brush head 308 can also be fixed to the gear ring 304.

It can be understood that the limiting housing part 3012 can also be installed on the main installation shell 3011, and is not limited to being connected by clamping. For example, it can also be connected to the main installation shell 3011 by threaded connection.
