[0031] This invention provides a dual-push electric hair coloring comb, such as... Figure 1-7 As shown, the device includes a hair dyeing tube 101, a comb post 106, a telescopic sleeve rod 112, and a telescopic push rod 116. A partition plate 122 is fixedly installed at the center of the hair dyeing tube 101, dividing the tube into two downward-opening push chambers 121. Push pistons 123 that can move up and down are installed in both push chambers 121. Connecting plates 124 are fixedly installed on the lower end faces of the push pistons 123. A push base 148 is installed below the hair dyeing tube 101, and a functional cavity 126 with an upward opening is installed in the push base 148. A support disc 137 is horizontally positioned above the functional cavity 126. Two limiting cylinders 114 are fixedly installed on the lower end face of the support disc 137. The limiting cylinders 114 are symmetrically positioned, forming an opening between the limiting cylinders 114 and the support disc 137. The lower limiting cavity 145 is equipped with a propulsion device 1001. Above the supporting disc 137, there is a telescopic push rod 116 that can move up and down. The upper end of the telescopic push rod 116 can be installed and connected to the connecting plate 124. The propulsion device 1001 can control and drive the telescopic push rod 116 to move up and down. The upper wall of the propulsion cavity 121 is connected to two outward-facing liquid outlet holes 128. The liquid outlet holes 128 on both sides are symmetrically positioned. The upper end of the hair dyeing tube 101 is equipped with a hair dyeing comb device 1002. The lower part of the hair dyeing comb device 1002 is connected to the liquid outlet holes 128 on both sides. The hair dyeing comb device 1002 can mix the hair dye and output it. A control switch 109 is fixed on one side of the outer end face of the propulsion base 148. A detachable mounting base plate 111 is installed at the bottom of the propulsion base 148.

[0032] It should be noted that the push piston 123 is a piston in the prior art, and the push piston 123 is in contact with the inner wall of the push chamber 121.

[0033] like Figures 1-3 As shown, two arc-shaped clamping plates 102 are fixedly provided on the upper end face of the hair dyeing tube 101. The two arc-shaped clamping plates 102 are symmetrically positioned, and each arc-shaped clamping plate 102 has an opposite opening mounting groove 108.

[0034] Furthermore, the hair dyeing comb device 1002 includes a vertical comb post 106, with a mounting plate 107 rotatably connected below the comb post 106. The mounting plate 107 can be snapped into the mounting groove 108 and installed and connected to the arc-shaped clamping plate 102. A spray chamber 105 is fixedly provided on one end face of the comb post 106. Several comb rods 104 are fixedly provided on the end face of the spray chamber 105 away from the comb post 106. The comb rods 104 are arranged in a matrix from top to bottom. A spray hole 103 is provided on the end face of the comb rod 104 away from the spray chamber 105. The spray hole 103 is located 0.5 mm to 3 mm away from the tip of the comb rod 104.

[0035] It should be specifically noted that the nozzle 103 is either elliptical or dot-shaped. When the nozzle 103 is dot-shaped, it can output a high-speed columnar liquid stream, which can make the hair dyeing efficiency higher. When the nozzle 103 is elliptical, it can output a columnar liquid stream with a larger scouring width under the equivalent cross-sectional area. Moreover, its position is set so that when the tip of the spray chamber 105 contacts the scalp surface, the nozzle 103 does not come into direct contact with the scalp.

[0036] like Figure 5 As shown, the mounting plate 107 is provided with two liquid guide tubes 129. The liquid guide tubes 129 on both sides are symmetrically positioned. The lower end of the liquid guide tube 129 is connected to the upper end of the liquid outlet 128. The comb column 106 is provided with a mixing chamber 131. The lower end of the mixing chamber 131 is connected to a mixing tube 130. The mixing tube 130 is connected to the liquid guide tubes 129 on both sides. The mixing chamber 131 is provided with a liquid mixer 132.

[0037] It is worth noting that the liquid mixer 132 can achieve the effect of mixing the input hair dye.

[0038] Furthermore, an output pipe 133 is provided above the spray chamber 105, and the upper part of the mixing chamber 131 is connected to the upper part of the output pipe 133. A vertical uniform delivery pipe 136 is provided on the side of the spray chamber 105 away from the comb post 106. The center position of one side of the uniform delivery pipe 136 is connected to the lower end of the output pipe 133, and the other side of the uniform delivery pipe 136 is connected to the comb rods 104 on each side.

[0039] Furthermore, the comb rod 104 is provided with a delivery tube 135, one end of which is connected to the uniform delivery tube 136, and the other end of which is connected to the spray hole 103.

[0040] like Figure 4 and Figure 6 as well as Figure 7 As shown, the propulsion device 1001 also includes a telescopic sleeve 112 rotatably disposed in the limiting cavity 145. The telescopic sleeve 112 is provided with a threaded groove 147 with an opening facing downward. The lower end of the telescopic push rod 116 extends into the threaded groove 147 and is fixedly connected to the limiting plate 127. The top opening of the telescopic sleeve 112 is provided with a thread at the connection between it and the telescopic push rod 116. The outer end face of the telescopic push rod 116 is provided with a thread. The telescopic push rod 116 and the telescopic sleeve 112 are threadedly connected.

[0041] Furthermore, the upper surface of the support disc 137 is provided with two propulsion gears 125, which are symmetrically positioned on both sides. The inner ring of the propulsion gears 125 is threaded. The top end of the telescopic sleeve 112 extends into the inner ring of the propulsion gears 125. The upper end of the telescopic sleeve 112 is threadedly connected to the shaft of the propulsion gears 125. The top end of the limiting cavity 145 is fixedly provided with a contact controller 146, and the bottom end of the telescopic sleeve 112 is fixedly provided with an annular limiting plate 113.

[0042] It should be further noted that the contact controller 146 is a contact sensor in the prior art.

[0043] When using this solution, after connecting the upper end of the telescopic push rod 116 to the connecting plate 124, the connecting plate 124 rotates, which in turn drives the telescopic sleeve rod 112 to rotate through meshing. At this time, the telescopic sleeve rod 112 is not limited and is driven to rotate. As the telescopic sleeve rod 112 rotates, it is connected to the top of the telescopic sleeve rod 112 through the threaded connection between the telescopic push rod 116 and the top of the telescopic sleeve rod 112. First, it drives the telescopic push rod 116 to move upward. When the telescopic push rod 116 moves to the upper limit position, the limiting plate 127 is engaged with the top of the threaded groove 147, and the telescopic sleeve rod 112 is limited to rotate. Then, as the subsequent propulsion gear 125 rotates, it is connected to the surface of the telescopic sleeve rod 112 through the internal tooth groove, which drives the telescopic sleeve rod 112 to move upward. This drives the telescopic push rod 116 to move telescopically, which in turn drives the telescopic sleeve rod 112 to move telescopically, thus pushing the propulsion device 1001 to move forward.

[0044] It is worth noting that multiple telescopic sleeves 112 can be fitted inside the limiting cavity 145. The limiting cavity 145 can be fitted with different inner diameters as needed. Thus, by combining multiple telescopic sleeves 112, the telescopic distance of the telescopic push rod 116 can be increased, thereby further expanding the propulsion distance of the propulsion device 1001. In other words, by using multiple stacked telescopic sleeves 112, the telescopic length can be increased, further expanding the propulsion distance of the propulsion device 1001.

[0045] Furthermore, a detachable closed cover plate 119 is installed on the upper end of the support disc 137. The closed cover plate 119 has two closed through holes 120 that are connected vertically. The upper end of the telescopic push rod 116 passes through the closed through holes 120.

[0046] It should be noted that the inner diameter of the closed through hole 120 is larger than the diameter of the telescopic sleeve 112, and the inner diameter of the closed through hole 120 can be changed according to process requirements.

[0047] Furthermore, a support plate 141 is fixedly provided on one side wall of the functional cavity 126, which provides support. A power motor 142 is fixedly provided on the upper end of the support plate 141. The power motor 142 is connected to the control switch 109. A power gear 140 is rotatably provided on one side of the upper surface of the support disc 137. The power gear 140 is located above the power motor 142 and is poweredly connected to the power motor 142. A support shaft 138 is rotatably provided inside the support disc 137. The support shaft 138 is located between the two sides of the push gear 125 and the power gear 140. A fixed gear 139 is provided on the outer end face of the support shaft 138. The fixed gear 139 meshes with the two sides of the push gear 125 and the power gear 140.

[0048] It should be further explained that there are mounting threads on the lower part of the propulsion cavity 121 and on the upper part of the outer end face of the propulsion base 148, which together can achieve the effect of rotational installation.

[0049] During operation, different dyeing reagents are added into the two side propulsion chambers 121. The propulsion base 148 is then installed and connected to the bottom of the dyeing cylinder 101 via threads. The top of the telescopic push rod 116 is connected to the connecting plate 124. The dyeing comb device 1002 is then installed above the dyeing cylinder 101, and the liquid outlets 128 on both sides are connected to the liquid guide pipes 129 on both sides. The manual control switch 109 is then activated, starting the power motor 142. The power motor 142 drives the power gear 140 to rotate, which in turn drives the fixed gear 139 to rotate, which in turn drives the two side propulsion gears 125 to rotate. The connecting plate 124 rotates, which in turn drives the telescopic sleeve rod 112 to rotate. Unrestricted and driven to rotate, the telescopic sleeve 112 rotates and is connected to the top of the telescopic sleeve 112 via the telescopic push rod 116 threaded connection. First, the telescopic push rod 116 moves upward. When the telescopic push rod 116 moves to the upper limit position, the limiting plate 127 is engaged with the top of the threaded groove 147, and the telescopic sleeve 112 is restricted to rotate. Then, as the subsequent propulsion gear 125 rotates, it is connected to the surface of the telescopic sleeve 112 via the internal tooth groove threaded connection, thereby driving the telescopic sleeve 112 to move upward. This allows the telescopic push rod 116 to move telescopically, and the telescopic sleeve 112 to continue to move telescopically, thus pushing the telescopic push rod 116 forward a longer distance. Furthermore, the hair dyeing comb device 1002 drives the telescopic push rod 116 to move telescopically, and simultaneously drives the propulsion pistons 123 on both sides to move forward.

[0050] At this time, the two push pistons 123 on both sides advance simultaneously, pushing the two types of hair dye upwards into the liquid outlets 128 on both sides, and then into the liquid guide tube 129. The two hair dyes are mixed through the connected mixing tube 130, and then gradually fed into the mixing chamber 131. The liquid mixer 132 ensures thorough mixing, and after the mixing from bottom to top is complete to achieve the desired hair dyeing effect, the mixed hair dye flows from the top of the mixing chamber 131 into the output tube 133. The hair dye is fed into the uniform delivery tube 136 to achieve a uniform output effect. The hair dye is pushed outward through the delivery tube 135 and finally discharged outward through the spray hole 103. During this process, the user holds the telescopic sleeve 112 and drives the comb rod 104 to contact the scalp surface, and starts to dye the hair from the roots, realizing automatic hair dyeing. As the subsequent piston 123 is gradually pushed forward, the hair dye is stably and continuously pushed into the mixing chamber 131, thereby achieving a stable hair dyeing process.

[0051] When the limit plate 113 moves to the upper limit, the limit plate 113 comes into contact with the lower end face of the contact controller 146, and the control switch 109 is disconnected by the contact controller 146, thereby stopping the power motor 142 from rotating.

[0052] After a hair dyeing session is completed, the user removes the telescopic sleeve 112 connecting the protective cover and closes the top opening of the liquid distribution tubes on both sides of the cavity 121, thus facilitating the storage of the hair dye and making it convenient for use in the next hair dyeing session.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
