The terms used in the specification of the invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. As used herein, the term “and/or” includes any and all combinations of one or more related listed items.
FIG. 1 shows a foam cleansing instrument 10 according to a preferred embodiment of the present invention.
The foam cleansing instrument 10 mainly includes a base 101, a liquid injection bottle 102, a cleansing head 103, and a foaming pump 104.
The base 101 has a bottle mounting position 1011, to smoothly support the liquid injection bottle 102 through the bottle mounting position 1011.
The liquid injection bottle 102 is detachably mounted in the bottle mounting position 1011 and enables a cleanser in the liquid injection bottle 102 to flow downward to a bottle mouth of the liquid injection bottle 102 by its own gravity. In this way, the cleanser in the liquid injection bottle 102 can be sucked without connecting a straw in the liquid injection bottle 102, that is, the cleanser in the liquid injection bottle 102 flows out to the bottle mouth and then is pumped.
The cleansing head 103 is arranged on the base 101 and configured to fit a human face to smear foam on the human face.
The foaming pump 104 is connected to the bottle mouth of the liquid injection bottle 102 through a liquid inlet pipe 105 and connected to the cleansing head 103 through a liquid outlet pipe 106; and at least one of the liquid inlet pipe 105 and the liquid outlet pipe 106 is connected to a foam maker 107, so that the cleanser on the cleansing head 103 is in a foaming state by foaming the cleanser by the foam maker 107, so as to improve the experience effect. It should be noted that, in this case, the liquid inlet pipe 105 only needs to be connected to the bottle mouth of the liquid injection bottle 102, that is, there is no need to arrange the straw exposed in the bottle mounting position 1011. In this way, when the liquid injection bottle 102 needs to be replaced with a new liquid injection bottle 102 (that is, the liquid injection bottle 102 is a disposable bottle), because no straw needs to be arranged on the base 101, a situation is avoided that unnecessary sanitation and hygiene operation is caused by cleanser adhesion to the straw, thereby improving convenience. In addition, each time the liquid injection bottle is replaced with a new liquid injection bottle 102, the operation is only to remove the old liquid injection bottle 102 from the bottle mounting position 1011, and then mount the new liquid injection bottle 102 in the bottle mounting position 1011, thereby making the operation of replenishing the cleanser especially convenient.
Referring to FIG. 1, preferably, when the liquid injection bottle 102 stands, the bottle mouth of the liquid injection bottle 102 is located at a maximum horizontal height of the liquid injection bottle 102 and at an edge of the liquid injection bottle 102. When the liquid injection bottle 102 is inversely mounted in the bottle mounting position 1011, the bottle mouth of the liquid injection bottle 102 is located at a minimum horizontal height of the liquid injection bottle 102. In this way, when the liquid injection bottle 102 is inverted, all the cleanser therein rushes to the bottle mouth, so that all the cleanser in the liquid injection bottle 102 can flow out.
Referring to FIG. 1, preferably, the foam cleansing instrument 10 further include a motor 108, a rotating shaft 109 in driving connection with the motor 108, a storage battery accommodated in the base 101, and a wireless charging seat detachably inserted in the base 101. The rotating shaft 109 is linked with the cleansing head 103. The motor 108 and the foaming pump 104 are connected to the storage battery. In this way, the motor 108 drives the rotating shaft 109 to rotate, and the rotating shaft 109 is linked with the cleansing head 103 to rotate, thereby improving smearing efficiency. It may be understood that, as an alternative to rotation, a vibration type of existing cleansing instruments is provided.
Referring to FIG. 2 and FIG. 8, preferably, the cleansing head 103 is provided with a plurality of brush rods 10321, the plurality of brush rods 10321 are encircled to form a multi-ring structure, brush rods 10321 located at a same ring are all at the same height, and heights of brush rods 10321 from an inner ring to an outer ring are gradually increased. In this way, the cleansing head 103 has a concave structure, so that when the cleansing head 103 rotates, the foamed cleanser moves in a radial direction of the cleansing head 103 under the action of a centrifugal force. Because the heights of the brush rods 10321 at the outer ring are higher than those of the brush rods 10321 at the inner ring, the foamed cleanser can be intercepted, thereby preventing the cleanser from being separated from the cleansing head 103. In addition, based on the rotation of the cleansing head 103, the cleanser on the cleansing head 103 can be distributed more evenly to improve the experience effect.
Referring to FIG. 8, preferably, for ease of cleaning, the cleansing head 103 is detachably connected to the base 101, for example, though clamping or magnetic connection. The brush rods 10321 are made of a silicone material, and the cleansing head 103 is provided with massage beads 1033. In this way, the brush rods 10321 made of the silicone material touch the human face relatively gently, so that the massage beads 1033 can also touch the face for massage while the cleanser is smeared.
Referring to FIG. 8, preferably, a plurality of massage beads 1033 are provided, the cleansing head 103 is provided with a plurality of silicone sleeves 10322, elastic members 1034 are accommodated in the silicone sleeves 10322, each of the massage beads 1033 is embedded in one silicone sleeve 10322, supported by the corresponding elastic member 1034 and wrapped by the silicone sleeve 10322, and part of the massage bead 1033 is leaked out of the silicone sleeve 10322. In this way, the massage beads 1033 have an elastic floating range, so that the massage beads 1033 can be prevented from hurting the human face through pressing. In a preferred layout, a plurality of massage beads 1033 are distributed in a circumferential array around an axis of the rotating shaft 109, so that the massage effect is relatively balanced. The elastic member 1034 may be a rubber block, a compression spring, or the like. More specifically, referring to FIG. 8 to FIG. 10, the cleansing head 103 includes a silicone brush holder 1031 and a silicone brush head 1032, where the silicone brush holder 1031 is provided with a plurality of positioning posts 10311, and the silicone brush head 1032 is detachably connected to the silicone brush holder 1031. The plurality of positioning posts 10311 are sleeved with the plurality of silicone sleeves 10322 respectively in a one-to-one correspondence, and the elastic member 1034 in each of the silicone sleeves 10322 is sleeved outside the corresponding positioning post 10311. In this way, the cleansing head 103 is divided into two main components, namely, the silicone brush holder 1031 and the silicone brush head 1032, so that the massage beads 1033 and the elastic members 1034 can be conveniently installed in the cleansing head 103. In addition, the elastic members 1034 are positioned by the positioning posts 10311, so that the elastic members 1034 can be prevented from being deviated. Further, referring to FIG. 8, an aperture of an opening 103221 of each of the silicone sleeves 10322 is smaller than that of a body 103222 of the silicone sleeve 10322. In this way, the opening 103221 of the silicone sleeve 10322 can prevent the massage beads 1033 from popping out of the silicone sleeve 10322.
Referring to FIG. 2, preferably, the rotating shaft 109 is axially provided with an accommodating through hole 1091, and the liquid outlet pipe 106 is sleeved in the accommodating through hole 1091; the foam cleansing instrument 10 further includes a gear transmission assembly 110, and the motor 108 is in transmission connection with the rotating shaft 109 through the gear transmission assembly 110. In this way, on the basis that the motor 108 drives the cleansing head 103 to rotate, the liquid outlet pipe 106 and the rotating shaft 109 are coaxially arranged, thereby improving compactness of the cleansing instrument.
Preferably, referring to FIG. 4 (for ease of understanding, referring to FIG. 2 and FIG. 5 when necessary), the gear transmission assembly 110 includes a gear box 111 fixed to the base 101 and a transmission gear set 112 accommodated in the gear box 111, and the motor 108 is accommodated in the gear box 111, and is in driving connection with the rotating shaft 109 through the transmission gear set 112; the gear box 111 is internally connected to a first compensation sealing ring 113, and the first compensation sealing ring 113 is arranged around a periphery of the rotating shaft 109; the first compensation sealing ring 113 is composed of a first annular fitting portion 1131, a first annular thin-walled portion 1132, and a first annular mounting portion 1133 that are connected in sequence in a radial direction of the first compensation sealing ring 113; the first annular fitting portion 1131 is sleeved on an outer wall of the rotating shaft 109 and closely fits the same; the first annular thin-walled portion 1132 is configured to avoid the first annular fitting portion 1131, so as to enable the first annular fitting portion 1131 to deform; and the first annular mounting portion 1133 is fixed to the gear box 111. In this way, when the rotating shaft 109 rotates at a high speed to swing, due to deformation of the first annular thin-walled portion 1132, the first annular fitting portion 1131 can be close to an outer wall of the rotating shaft 109, thereby ensuring the sealing effect. In this way, even if the foamed cleanser flows in from the cleansing head 103 along the outer wall of the rotating shaft 109, the cleanser will be intercepted by the first annular fitting portion 1131, thereby ensuring that components in the gear box 111 are not eroded.
Further, referring to FIG. 4 and FIG. 5, the transmission gear set 112 includes a first gear 1121 and a second gear 1122 integrally formed and coaxial with the first gear 1121, and the second gear 1122 is in transmission connection with the rotating shaft 109. The transmission gear set 112 further includes a third gear 1123 meshing with the second gear 1122, a fourth gear 1124 integrally formed and coaxial with the third gear 1123, and a fifth gear 1125 meshing with the fourth gear 1124 and integrally formed with the rotating shaft 109. In this way, through the coaxial arrangement of the two gears, the compactness of the transmission gear set 112 is greatly improved, so that a rotating speed of the cleansing head 103 can be greatly reduced, to control the rotating speed of the cleansing head 103 within a reasonable range.
Preferably, referring to FIG. 2 and FIG. 5, the gear box 111 is mounted in the base 101, and a cover 1012 of the base 101 abuts against the first compensation sealing ring 113 and axially limits the first compensation sealing ring 113. In this way, the cover 1012 is radially sealed by the first compensation sealing ring 113, so that the base 101 has a waterproof function.
Referring to FIG. 2, preferably, the liquid outlet pipe 106 includes a hard pipe 1061 and a hose 1062. The hard pipe 1061 is sleeved in the accommodating through hole 1091, and the hose 1062 communicates with the hard pipe 1061. The hard pipe 1061 has an L-shaped structure. In this way, the hard pipe 1061 can be sleeved in the rotating shaft 109 and kept in a static state, while the hose 1062 can be connected to the foaming pump 104.
Referring to FIG. 2, in order to smoothly limit the rotating shaft 109, the gear box 111 is provided with an annular limit groove 1111, and the rotating shaft 109 is sleeved in the annular limit groove 1111. In this case, to perform waterproof sealing on the rotating shaft 109, preferably, the gear box 111 is internally provided with a second compensation sealing ring 115, and the second compensation sealing ring 115 is located below the first compensation sealing ring 113, sleeved on a periphery of the annular limiting groove 1111 and arranged around the periphery of the rotating shaft 109. Specifically, the second compensation sealing ring 115 is composed of a second annular fitting portion 1151, a second annular thin-walled portion 1152, and a second annular mounting portion 1153 that are connected in sequence in a radial direction of the second compensation sealing ring 115. The second annular fitting portion 1151 is sleeved on the outer wall of the rotating shaft 109 and closely fits the same; the second annular thin-walled portion 1152 is configured to avoid the second annular fitting portion 1151 so that the second annular fitting portion 1151 can be deformed; and the second annular mounting portion is fixed to the gear box 111. Similarly, when the rotating shaft 109 rotates at a high speed to swing, due to deformation of the second annular thin-walled portion 1152, the second annular fitting portion 1151 can be close to the outer wall of the rotating shaft 109, thereby ensuring the sealing effect. In this way, even if the foamed cleanser flows in from the cleansing head 103 along the accommodating through hole 1091, it will be intercepted by the first annular fitting portion 1131, thus ensuring that the components in the gear box 111 are not eroded.
Referring to FIG. 5, to prevent the cleanser from being directly sprayed, preferably, the foam cleansing instrument 10 further includes an axial blocking cap 114, where a connecting portion of the axial blocking cap 114 is connected to an outlet of the liquid outlet pipe 106; a cap body 1141 of the axial blocking cap 114 is located at the outlet of the liquid outlet pipe 106, to prevent the cleanser in the liquid outlet pipe 106 from being sprayed in an axial direction of the liquid outlet pipe 106; the axial blocking cap 114 is provided with a liquid outlet groove 1142 extending in the axial direction of the liquid outlet pipe 106, and the liquid outlet groove 1142 communicates with the liquid outlet pipe 106 and an external environment, so that the cleanser in the liquid outlet pipe 106 is capable of flowing out in a radial direction of the liquid outlet pipe 106. In this way, with the rotation of the cleansing head 103, the cleanser is distributed more evenly in the radial direction.
Referring to FIG. 6 and FIG. 7, preferably, the foam maker 107 includes a foaming pipe 1071 and at least two foam meshes 1072 accommodated in the foaming pipe 1071, and the two foam meshes 1072 are spaced to form a foaming cavity 1073. It may be understood that each of the foam meshes 1072 may be a porous plate, and the cleanser can be foamed by distributing the high-speed cleanser through the foam meshes 1072. A supporting spring 1074 is accommodated in the foaming cavity 1073, and two ends of the supporting spring 1074 each abut against one of the foam meshes 1072. In this way, the cleanser can be fully foamed by the foaming of the two foam meshes 1072.
Preferably, referring to FIG. 6 and FIG. 7, the foaming pipe 1071 includes a first pipe section 10711 and a second pipe section 10712, where the first pipe section 10711 is provided with a liquid inlet channel 107111, the foaming cavity 1073 is provided in the second pipe section 10712, and the second pipe section 10712 is provided with a liquid outlet channel 107121; the liquid inlet channel 107111, the foaming cavity 1073, and the liquid outlet channel 107121 communicate with each other in sequence; and an inn diameter of the liquid inlet channel 107111 and an inner diameter of the liquid outlet channel 107121 are both small than that of the foaming cavity 1073. In this way, when the cleanser flows into the foaming cavity 1073 from the liquid inlet channel 107111, according to a flow continuity equation, the flow rate of the cleanser decreases due to the expansion of a cross section, so that the cleanser can be fully foamed in the foaming cavity 1073. After the foaming is completed, the cleanser flows out to the liquid outlet channel 107121, and therefore the flow rate restores to an initial value based on the reduction of the cross section. Therefore, to restore the speed to the initial value, preferably, the inner diameter of the liquid inlet channel 107111 and the inner diameter of the liquid outlet channel 107121 are equal.
Referring to FIG. 6 and FIG. 7, one of the first pipe section 10711 and the second pipe section 10712 is provided with a ring groove 107122, the other is provided with a flange 107112, and the flange 107112 is clamped in the ring groove 107122. In this way, hermetic clamping can be implemented. To facilitate the connection of the foaming pipe 1071 into the pipe section of the liquid inlet pipe 105 and prevent the foaming pipe from falling off easily, two ends of the foaming pipe 1071 are provided with cone frustum connecting portions 10713, and a diameter of each of the cone frustum connecting portions 10713 gradually increases from outside to inside in the axial direction of the foaming pipe 1071. The foam meshes 1072 are made of a metal material. Preferably, one of the foam meshes 1072 is axially limited by a cavity wall of the foaming cavity 1073, and the other foam mesh 1072 is axially limited by the first pipe section 10711. In this way, the foam meshes 1072 can be stably fixed.
Referring to FIG. 1, the base 101 includes a handle 1013, a left fork 1014 connected to the top of the handle 1013 and extending obliquely upward, and a right fork 1015 connected to the top of the handle 1013 and extending obliquely upward, so that an outer contour of the base 101 has a Y-shaped structure. The bottle mounting position 1011 is located at the left fork 1014, the right fork 1015 is provided with a cleansing head 103, and the cleansing head 103 is provided with brush rods 10321. In this way, when the handle 1013 is grasped by a human hand, the liquid injection bottle 102 is placed obliquely with respect to the horizontal plane, so that the liquid injection bottle has a better stress state and does not fall off easily. In this case, it is convenient for a user to use a device.
The foregoing implementations are only preferred implementations of the present invention, and cannot be used to limit the protection scope of the present invention. Any immaterial changes and replacements made by a person skilled in the art on the basis of the present invention fall within the protection scope of the present invention.
