Description

Technical Field

[0001] The utility model relates to the technical field of beauty instruments, in particular to an automatic facial deep cleaning device. Background Art

[0002] An existing facial washing device includes a housing, a negative pressure pump, an electronic control device and a cleaning head. The negative pressure pump and the electronic control device are placed in the housing, and the cleaning head is fixed to the head of the housing. A detachable container is provided at the rear of the housing, and the container includes a cleaning liquid chamber and a sewage chamber. A working chamber is formed in the cleaning head, and the front end of the working chamber is open to form a suction port. The bottom wall of the working chamber is provided with a positive pressure hole and a negative pressure hole for supplying the cleaning liquid. One end of the negative pressure tube is connected to the negative pressure hole and connected to the negative pressure pump and then extends into the sewage chamber. One end of the positive pressure tube is connected to the positive pressure hole and the other end is connected to the cleaning liquid chamber.

[0003] When using the device, the suction port of the working chamber of the cleaning head is placed close to the skin, and the negative pressure pump can form a negative pressure in the working chamber after it is started; when suction is required for blackheads, the electric control valve is closed at this time to prevent the cleaning liquid from entering the working chamber, and when rinsing is required after the blackheads are adsorbed, the electric control valve is opened to pump the cleaning liquid into the working chamber under negative pressure, cleaning the skin while removing the blackheads, and the sewage is finally discharged into the sewage chamber.

[0004] The problem with the existing facial cleansing device is that after the user presses the mode button, the electronically controlled valve switch is electrically controlled according to the button signal obtained to achieve the mode conversion between adsorbing blackheads and rinsing and cleaning, which is inconvenient to operate. Utility Model Content

[0005] The utility model aims to provide an automatic facial deep cleaning device which reduces the difficulty of operation.

[0006] The automatic facial deep cleaning device provided by the utility model comprises a cleaning head, which comprises a positive pressure channel, a working chamber and a negative pressure channel which are connected in sequence, and the working chamber has an adsorption port; the handheld instrument also comprises a valve core; the positive pressure channel comprises a first channel portion and a second channel portion, the valve core is floatingly installed in the second channel portion along a first direction, the second channel portion passes through the internal space of the automatic facial deep cleaning device and the working chamber along the first direction, and the first channel portion and the second channel portion are connected through a connecting hole arranged along the second direction; a flow channel is arranged in the valve core, and the flow channel has a transverse flow channel portion which opens along the second direction and a longitudinal flow channel portion which passes through along the first direction, and the transverse flow channel portion is connected with the longitudinal flow channel portion; under the pressure difference between the internal space and the working chamber, the valve core moves along the first direction and connects the connecting hole with the inlet of the transverse flow channel portion.

[0007] It can be seen from the above scheme that the utility model realizes the automatic switching of the working modes of adsorbing blackheads and cleaning based on a purely mechanical structure. Specifically, when the negative pressure pump is started, the cleaning head is placed close to the skin to generate negative pressure in the working chamber and adsorb blackheads. During the process, the negative pressure in the working chamber gradually increases, so that a pressure difference is formed between the internal space of the device and the working chamber. When the negative pressure in the working chamber reaches a certain value, and the force exerted on the valve core under the pressure difference exceeds the holding force of the valve core, the valve core can be driven to move, and the connecting hole that was originally misplaced and not connected can be connected with the transverse flow channel part, and the cleaning liquid is sequentially supplied to the working chamber through the positive pressure channel and the flow channel, so as to perform flushing and cleaning work. Therefore, the automatic facial deep cleaning device of the utility model automatically switches the working mode to reduce the difficulty of operation.

[0008] A further solution is that the handheld instrument further comprises a breathable membrane, and the breathable membrane cooperates with the port of the longitudinal flow channel portion facing the inner space.

[0009] As can be seen from the above, the provision of a breathable membrane is more conducive to the formation of a pressure difference between the internal space and the working chamber while ensuring the ventilation effect. In addition, it also plays a role in space isolation, which is conducive to the formation of a sterile environment.

[0010] A further solution is that the handheld instrument further comprises an elastic member, which is arranged in the second channel portion and abuts against the valve core, and the floating of the valve core is achieved by utilizing the force of the elastic member.

[0011] As can be seen from the above, under this arrangement, a simple mechanical structure is used to realize the floating installation of the valve core, the valve core that is not subjected to the pressure difference force remains in the disconnected position, and the pressure difference force overcomes the force of the elastic member to cause the valve core to move.

[0012] A further solution is that the handheld instrument also includes a retaining ring, which is arranged in the second channel portion, and the second channel portion is connected to the working chamber through the center hole of the retaining ring; the elastic member abuts between the retaining ring and the valve core.

[0013] A further solution is that the retaining ring is detachably connected to the cleaning head, and the elastic member can be replaced after the retaining ring is removed.

[0014] As can be seen from the above, this arrangement facilitates the installation of the elastic member; in addition, the detachable retaining ring also facilitates the replacement of elastic members with different elasticities according to different negative pressures to meet the usage requirements of different users.

[0015] A further solution is that the elastic member is a spring, the valve core includes a main body and a boss protruding from the outer periphery of the main body, and the spring is sleeved outside the main body and abuts against the boss.

[0016] As can be seen from the above, under this arrangement, in the relatively narrow second channel portion, a smaller space is utilized to complete the installation of the spring, ensuring that the flow channel has a sufficiently large cross-section, ensuring the liquid supply flow rate and flow rate, and ensuring the flushing effect.

[0017] Another further solution is that the cleaning head includes a bottom wall and a peripheral wall, and a working chamber is formed between the bottom wall and the peripheral wall; the cleaning head also includes a vortex extending along a spiral line, the vortex protrudes from the bottom wall and is located on the inner periphery of the peripheral wall, and the vortex spacing forms a spiral channel in the working chamber.

[0018] A further solution is that the spiral channel includes an extension start end and an extension end, the extension end is located in the middle of the working chamber, the extension end is located at the periphery of the working chamber, the positive pressure channel is connected to the extension start end, and the negative pressure channel is connected to the extension end.

[0019] As can be seen from the above, under this setting, the cleaning liquid entering the working chamber will flow along the spiral line, with better fluidity and better cleaning effect; in a further solution, this setting can ensure that the cleaning liquid flows completely through the entire spiral channel, and the curvature of the outer periphery is smaller to avoid affecting the flow rate of the entering cleaning liquid.

[0020] A further solution is that the handheld instrument also includes a shell, on which a first tube body and a second tube body are provided, the shell is connected to the cleaning head, the outlet of the first tube body is connected to the positive pressure channel, and the inlet of the second tube body is connected to the negative pressure channel.

[0021] A further solution is that the handheld instrument also includes a negative pressure pump, a cleaning liquid container, a sewage container and a tube group; through the tube group, the cleaning liquid container is connected to the inlet of the first tube body, and the negative pressure end of the negative pressure pump, the sewage container and the outlet of the second tube body are connected in sequence.

[0022] It can be seen from the above that, compared with the background technology, the utility model simplifies the pipe connection method and reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS

The spiral channel 220 includes an extension start end 220a and an extension end 220b, the extension end 220b is located in the middle of the working chamber 20, and the extension end 220b is located at the outer periphery of the working chamber 20, the outlet of the positive pressure channel 21 is connected to the extension start end 220a, and the inlet of the negative pressure channel 23 is connected to the extension end 220b.

[0034] See also Figures 3 to 6 The positive pressure channel 21 includes a first channel portion 211 and a second channel portion 212 which are parallel to each other and communicate with each other. The inlet of the first channel portion 211 is connected to the outlet of the first tube body 101. The second channel portion 212 runs through the inner space 103 of the housing 10 and the working chamber 20 along the first direction. The first channel portion 211 and the second channel portion 212 are communicated through a communication hole 213 arranged along the second direction. The lower end of the first channel portion 211 is blocked by a plug 25.

[0035] The retaining ring 31, the spring 32, the valve core 33 and the breathable membrane 34 are all installed in the second channel portion 212. The valve core 33 includes a main body 331 and a boss 332 protruding from the outer periphery of the main body 331. The flow channel 330 is arranged in the main body 331. The flow channel 330 has a transverse flow channel portion 3301 opening along the second direction and a longitudinal flow channel portion 3302 penetrating along the first direction. The transverse flow channel portion 3301 is connected to the longitudinal flow channel portion 3302.
