Description

Technical Field

[0001] This invention relates to the field of personal care technology, and in particular to a blackhead adsorption device and its control method. Background Technology

[0002] With social progress and development, people's pursuit of beauty is increasing. Given this desire for beauty, various beauty and skincare devices have emerged and gained widespread acceptance. For those with excessive facial oil secretion, blackheads have always been a problem. The advent of suction-type blackhead removers makes it easy to remove blackheads and oil from pores, keeping the face clean and refreshed. Currently, most blackhead removers on the market are suction-type. The suction head is in close contact with the skin, and the air pump continuously draws air, making the air pressure inside the suction head lower than the external air pressure. This pressure causes blackheads and oil to be drawn out of the pores. However, with continuous use, because the duration of suction cannot be monitored, users can easily leave the same spot suctioned for too long, leading to ruptured capillaries and causing redness similar to that after cupping. Redness on the face greatly affects the user experience, so current products still have significant shortcomings in terms of user protection. Existing blackhead suction devices detect air pressure using the principle of capacitance, but this capacitance detection method has certain drawbacks when used in blackhead suction devices. Existing blackhead removers, in order to achieve a better user experience, moisturize the area being treated during the removal process, causing blackheads and oil on the skin's surface to be drawn to the water tank along with the moisture. Therefore, the suction head assembly of the blackhead remover contains not only air but also moisture and oil, resulting in inaccurate capacitance detection due to the presence of two variables: the dielectric constant ε and the inter-electrode spacing d. This can lead to a certain degree of misjudgment. Summary of the Invention

[0003] The main objective of this invention is to propose a blackhead adsorption device and its control method, which overcomes the shortcomings of existing blackhead adsorption devices. When the suction head assembly continuously adsorbs the skin for too long, it can automatically stop drawing air from the suction head assembly and automatically draw in atmospheric air to the suction head assembly to achieve a rapid balance of air pressure inside and outside the suction head assembly.

[0004] The present invention adopts the following technical solution:

[0005] On one hand, a blackhead removal device includes a suction head assembly and an air pump, and further includes a control module, an air pressure communication section, and an infrared sensor. The air pressure communication section includes an elastic component, a first opening, and a second opening. The air pressure communication section is connected to the suction head assembly through the first opening and to the air pump through the second opening. The elastic component is disposed on the surface of the air pressure communication section to deform when the internal air pressure changes. The infrared sensor is disposed opposite the elastic component to convert the detected infrared signal into a corresponding electrical signal and send it to the control module. The control module determines the continuous adsorption time of the suction head assembly based on the change of the electrical signal, and controls the air pump to pump, suck, or shut down based on the continuous adsorption time.

[0006] Preferably, the elastic component is covered with an elastic diaphragm; the material of the elastic diaphragm includes NBR, EPDM or silicone.

[0007] Preferably, except for the elastic component, the other parts of the air pressure communication part are made of rigid plastic, including PC, ABS, PP or acrylic.

[0008] Preferably, when the elastic component does not deform, the relative distance between the infrared sensor and the elastic component is 12mm-18mm.

[0009] Preferably, the blackhead adsorption device further includes: a prompting module; after the control module determines that the continuous adsorption time of the suction head assembly is greater than or equal to a preset time based on the change of the electrical signal, it controls the prompting module to generate an audible / visual prompt.

[0010] Preferably, the elastic component includes one or more, and an infrared sensor is provided for each elastic component.

[0011] Preferably, when the control module determines based on the change in the electrical signal that the continuous adsorption time of the suction head assembly has not reached the preset time, it controls the air pump to draw air, so as to reduce the internal air pressure of the air pressure communication part and cause the elastic diaphragm to indent inward; when the control module determines based on the change in the electrical signal that the continuous adsorption time of the suction head assembly is greater than or equal to the preset time, it controls the air pump to draw air, so as to draw external air into the suction head assembly.

[0012] Preferably, the blackhead adsorption device further includes: an air valve; the air pressure communication part further includes a third opening; the air valve is connected to the third opening of the air pressure communication part; after the control module determines that the continuous adsorption time of the suction head assembly is greater than or equal to a preset time based on the change of the electrical signal, it controls the air valve to open so as to draw in the outside atmosphere.

[0013] On the other hand, a method for controlling a blackhead removal device includes:

[0014] Upon receiving the blackhead removal command, it controls the air pump to start suction and controls the infrared sensor to start detection.

[0015] Once it is determined that the electrical signal detected by the infrared sensor has decreased to a preset value, the calculation of the continuous adsorption time of the suction head assembly is initiated.

[0016] Once it is determined that the continuous adsorption time is greater than or equal to the preset time, the air pump is controlled to stop pumping air, and atmospheric air is drawn into the suction head assembly.

[0017] Preferably, the infrared sensor is positioned directly opposite an elastic component; the elastic component is disposed on the surface of an air pressure communication section; the air pressure communication section is connected to the suction head assembly through a first opening, and the air pressure communication section is connected to the air pump through a second opening; when the internal air pressure of the air pressure communication section decreases, the elastic component is recessed inward.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention detects the change in the relative distance between the infrared sensor and the elastic component and converts it into a corresponding electrical signal to feed back to the control module. The control module uses this to determine the continuous adsorption time of the suction head assembly on the skin. If the continuous adsorption time reaches the preset time, the control stops drawing air from the suction head assembly and controls the intake of atmospheric air into the suction head assembly to achieve a rapid balance of air pressure inside and outside the suction head assembly, so that the suction head assembly no longer adsorbs the skin and avoids damage to the skin.

[0020] (2) The present invention is simple to implement. It only requires adding an air pressure connection part with an elastic component between the suction head assembly and the air pump, and setting an infrared sensor at a certain distance from the elastic component. The continuous adsorption time can be obtained according to the change in the relative distance between the elastic component and the infrared sensor.

[0021] (3) After the air pump stops drawing air from the suction head assembly, the present invention can also control the air pump to draw air into the suction head assembly to achieve a rapid balance of air pressure inside and outside the suction head assembly, thereby enabling rapid resumption of use; it can also control the air pump to stop drawing air from the suction head assembly after the air pump stops drawing air from the suction head assembly, and draw external air into the suction head assembly by opening the air valve to achieve a rapid balance of air pressure inside and outside the suction head assembly.

[0022] (4) After determining that the continuous adsorption time of the suction head assembly is greater than or equal to a preset time, the present invention controls the generation of sound / light prompts so that the user can have an intuitive understanding of the usage status.

[0023] (5) The present invention can provide multiple elastic components on the air pressure communication part, each elastic component corresponding to an infrared sensor. Providing multiple infrared sensors can make the detection more accurate.

[0024] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are listed below.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] See Figures 1 to 3 As shown, this embodiment of a blackhead adsorption device includes a suction head assembly 10 and an air pump 20, as well as a control module 30, an air pressure communication section 40, and an infrared sensor 50. The air pressure communication section 40 includes an elastic component 401, a first opening 402, and a second opening 403. The first opening 402 of the air pressure communication section 40 is connected to the suction head assembly 10, and the second opening 403 of the air pressure communication section 40 is connected to the air pump 20. The elastic component 401 is disposed on the surface of the air pressure communication section 40 to deform when the internal air pressure of the air pressure communication section 40 changes. The infrared sensor 50 is disposed opposite the elastic component 401 to convert the detected infrared signal into a corresponding electrical signal and send it to the control module 30. The control module 30 determines the continuous adsorption time of the suction head assembly 10 based on the change of the electrical signal, and controls the air pump 20 to pump, aspirate, or shut down based on the continuous adsorption time.

[0037] Specifically, when the blackhead adsorption device starts working, the air pump 20 starts to draw air. Since the air pressure communication part 40 is connected to both the air pump 20 and the suction head assembly 10, the air pressure in both the air pressure communication part 40 and the suction head assembly 10 will decrease when the air pump 20 draws air. As the air pressure decreases, the elastic member 401 will indent inward, thereby increasing the relative distance between it and the infrared sensor 50. That is, the infrared signal detected by the infrared sensor 50 will become weaker, i.e., the electrical signal will become smaller. When the adsorption reaches a stable state, the elastic member 401 will no longer indent inward, and the electrical signal detected by the infrared sensor 50 will also reach a stable state.

[0038] The electrical signal can be either a voltage signal or a current signal; the specific type of output signal is determined by the model of the infrared sensor 50. This embodiment uses voltage information as an example. When air is not being pumped, the infrared sensor 50 feeds back a voltage signal to the control module 30 based on the detected infrared signal. When air pumping begins, due to the increased relative distance, the voltage signal fed back by the infrared sensor 50 to the control module 30 gradually decreases. When the voltage signal decreases to a preset value or stops changing, it is considered to be in a continuous adsorption state, and the continuous adsorption time is started. When the continuous adsorption time reaches the preset time, the control module 30 controls the air pump 20 to stop pumping. After the air pressure inside and outside the suction head assembly 10 is balanced, the elastic component 401 can return to its initial state.

[0039] In this embodiment, the elastic component 401 includes an elastic diaphragm; the material of the elastic diaphragm includes NBR, EPDM, or silicone. In this embodiment, the air pressure communication part 40 can be configured as a cuboid shape, and the inner cavity of the air pressure communication part 40 is hollow to allow the elastic module to be recessed inward. In this embodiment, the central portion of one surface is configured as the elastic diaphragm; in another embodiment, one surface can also be configured as the elastic diaphragm, depending on the specific needs.

[0040] Furthermore, the shape of the elastic diaphragm can be circular, square, or irregular, and can be set according to specific needs.

[0041] Furthermore, apart from the elastic component 401, the other parts of the air pressure connection part 40 are made of hard plastic, including PC, ABS, PP or acrylic, which makes the entire air pressure connection part 40 lighter and will not affect the use of the blackhead adsorption device.

[0042] In this embodiment, in order to improve the detection performance of the infrared sensor 50, when the elastic member 401 does not deform, the relative distance between the infrared sensor 50 and the elastic member 401 is set to 12mm-18mm, and there are no obstructions between them.

[0043] In this embodiment, the blackhead adsorption device further includes: a prompting module (not shown in the figure); after the control module 30 determines that the continuous adsorption time of the suction head assembly 10 is greater than or equal to a preset time based on the change of the electrical signal, it controls the prompting module to generate an audible / visual prompt.

[0044] Specifically, sound prompts can be used, such as "Adsorption time too long, please stop adsorption" or "Adsorption time too long, please move to other parts of the face," etc. Light prompts can also be used, or both sound and light prompts can be used simultaneously.

[0045] In this embodiment, the elastic component 401 is a single unit, and a corresponding infrared sensor 50 is also provided for ease of calculation. In other embodiments, to ensure accurate detection, elastic diaphragms can be provided on multiple surfaces of the air pressure communication part 40, and multiple corresponding infrared sensors 50 can be provided. This allows for averaging the electrical signals fed back by multiple infrared sensors 50 to make the calculation results more accurate, or to use the detection results of other sensors when one infrared sensor 50 fails or the elasticity of the elastic diaphragm on one surface is poor.

[0046] In this embodiment, in order to achieve rapid balance of air pressure inside and outside the suction head assembly 10, the control module 30 determines that the continuous adsorption time of the suction head assembly 10 is greater than or equal to a preset time based on the change of the electrical signal, controls the air pump 20 to stop drawing air from the suction head assembly 10, and then controls the air pump 20 to reverse so as to draw external air into the suction head assembly 10.

[0047] See Figure 4 As shown in this embodiment, a control method for a blackhead adsorption device includes:

[0048] S401 receives the blackhead adsorption command, controls the air pump to start suction, and controls the infrared sensor to start detection.

[0049] S402, when it is determined that the electrical signal detected by the infrared sensor has decreased to a preset value, the calculation of the continuous adsorption time of the suction head assembly is started;

[0050] S403: When it is determined that the continuous adsorption time is greater than or equal to the preset time, the air pump is controlled to stop pumping air and the air is drawn into the suction head assembly.

[0051] In this embodiment, the main body implementing the control method of a blackhead adsorption device can be the control module as described above.

[0052] Specifically, the infrared sensor is positioned directly opposite an elastic component; the elastic component is disposed on the surface of an air pressure communication section; the first opening of the air pressure communication section is connected to the suction head assembly, and the second opening of the air pressure communication section is connected to the air pump; when the internal air pressure of the air pressure communication section decreases, the elastic component is recessed inward.

[0053] The specific structure and positional relationship of the air pressure connection part, the elastic component and the infrared sensor are described in the description of a blackhead adsorption device, and will not be repeated in this embodiment.

[0054] Further, see Figure 5 As shown, the detailed workflow of the control method for a blackhead adsorption device in this embodiment is as follows:

[0055] S501, Blackhead adsorption device is turned on;

[0056] S502, the control module controls the air pump to start working and begin pumping air;

[0057] S503, the control module controls the infrared sensor to work and feeds back the detected voltage signal to the control module;

[0058] S504, the control module determines whether the voltage signal has reached a first preset value (1.024V in the attached figure, 1.024V is only an embodiment for convenience of explanation, and other voltage values ​​may also be used). If it has not reached the value, it is determined that the device is not yet in the adsorption state, and proceeds to S502; if it has reached the first preset value, it is determined that the device is in the adsorption state, and proceeds to S505.

[0059] S505, the control module continues to determine whether the voltage signal has reached the second preset value based on the collected data. If it has not reached the second preset value, proceed to S502; if it has reached the second preset value (0.8V in the attached figure, 0.8V is only an embodiment for convenience of explanation, and other voltage values ​​may also be used), it is determined that it is in a continuous adsorption state, and the continuous adsorption time t is timed, and proceed to S506.

[0060] S506, the control module determines whether the continuous adsorption time has reached the preset time. If it has not reached the preset time, proceed to S502; if it has reached the preset time, issue a prompt to the user.

[0061] S507, the control module controls the air pump to stop working;

[0062] S508, the control module controls the intake of air into the suction head assembly.

[0063] In this embodiment, in order to achieve rapid balance of air pressure inside and outside the suction head assembly, the control module determines that the continuous adsorption time of the suction head assembly is greater than or equal to a preset time based on the change of the electrical signal. Then, it controls the air pump to stop drawing air from the suction head assembly and controls the air pump to reverse so as to draw external air into the suction head assembly.

[0064] See Figure 6 The figure shows the relative distance between the infrared sensor and the elastic component in the embodiment (see Figure 1). Figure 3 The graph shows the relationship between the distance between the infrared sensor and the elastic component and the voltage signal fed back by the infrared sensor. It can be seen from the graph that when the relative distance between the infrared sensor and the elastic component is close, the voltage signal detected by the infrared sensor is large. As the relative distance increases, the voltage signal detected by the infrared sensor decreases. When the elastic diaphragm deforms to a certain extent, it no longer deforms, the relative distance no longer changes, and the detected voltage signal also no longer changes.

[0065] This invention uses an infrared sensor to detect changes in the relative distance to the elastic component and converts them into corresponding electrical signals that are fed back to the control module. The control module uses this signal to determine the duration of the suction head assembly's adhesion to the skin. If the duration of adhesion reaches a preset time, the control module stops drawing air from the suction head assembly and reverses the air pump to draw in atmospheric air to the suction head assembly to achieve a rapid balance of air pressure inside and outside the suction head assembly. This prevents the suction head assembly from adhering to the skin and avoids causing damage to the skin.

[0066] Example 2

[0067] The difference between this embodiment and Embodiment 1 is that an additional opening (third opening 404) is made on the air pressure communication part 40. The third opening 404 is connected to an air valve 60 through a pipe. When the air valve 60 is opened, it can draw in air.

[0068] For details, see Figure 7 and Figure 8 As shown, this embodiment discloses a blackhead adsorption device, including a suction head assembly 10 and an air pump 20, as well as a control module 30, an air pressure communication section 40, and an infrared sensor 50. The air pressure communication section 40 includes an elastic component 401. The first opening 402 of the air pressure communication section 40 is connected to the suction head assembly 10, and the second opening 403 of the air pressure communication section 40 is connected to the air pump 20. The elastic component 401 is disposed on the surface of the air pressure communication section 40 to deform when the internal air pressure of the air pressure communication section 40 changes. The infrared sensor 50 is disposed opposite the elastic component 401 to convert the detected infrared signal into a corresponding electrical signal and send it to the control module 30. The control module 30 determines the continuous adsorption time of the suction head assembly 10 based on the change of the electrical signal, and controls the air pump 20 to pump, aspirate, or shut down based on the continuous adsorption time.

[0069] In this embodiment, the blackhead adsorption device further includes: an air valve 60; the air valve 60 is connected to the third opening 404 of the air pressure communication part 40; after the control module 30 determines that the continuous adsorption time of the suction head assembly 10 is greater than or equal to a preset time based on the change of the electrical signal, it controls the air pump 20 to stop and simultaneously controls the air valve 60 to open so as to draw external air into the suction head assembly 10.

[0070] It should be noted that, in order to speed up the balancing process, the air pump 20 can be controlled to reverse and draw in air, while the air valve 60 can be opened at the same time, depending on the specific needs.

[0071] Same as Example 1, see Figure 4 As shown in this embodiment, a control method for a blackhead adsorption device includes:

[0072] S401 receives the blackhead adsorption command, controls the air pump to start suction, and controls the infrared sensor to start detection.

[0073] S402, when it is determined that the electrical signal detected by the infrared sensor has decreased to a preset value, the calculation of the continuous adsorption time of the suction head assembly is started;

[0074] S403: When it is determined that the continuous adsorption time is greater than or equal to the preset time, the air pump is controlled to stop pumping air and the air is drawn into the suction head assembly.

[0075] In this embodiment, the main body implementing the control method of a blackhead adsorption device can be the control module as described above.

[0076] Specifically, the infrared sensor is positioned directly opposite an elastic component; the elastic component is disposed on the surface of an air pressure communication section; the first opening of the air pressure communication section is connected to the suction head assembly, and the second opening of the air pressure communication section is connected to the air pump; when the internal air pressure of the air pressure communication section decreases, the elastic component is recessed inward.

[0077] In this embodiment, controlling the intake of air into the suction head assembly is specifically achieved by the control module determining, based on the change in the electrical signal, that the continuous adsorption time of the suction head assembly is greater than or equal to a preset time, then controlling the air pump to stop and simultaneously controlling the air valve to open, so as to draw external air into the suction head assembly.

[0078] The specific structure and positional relationship of the air pressure connection part, the elastic component and the infrared sensor are described in the description of a blackhead adsorption device, and will not be repeated in this embodiment.

[0079] For a detailed workflow of the control method of the blackhead adsorption device in this embodiment, please refer to [link / reference]. Figure 6 As shown.

[0080] In this embodiment, in order to achieve rapid balance of air pressure inside and outside the suction head assembly, the control module determines that the continuous adsorption time of the suction head assembly is greater than or equal to a preset time based on the change of the electrical signal. Then, it controls the air pump to stop drawing air from the suction head assembly, and then controls the air pump to stop. At the same time, it controls the air valve to open so as to draw in the outside atmosphere into the suction head assembly.

[0081] This invention uses an infrared sensor to detect changes in the relative distance to the elastic component and converts them into corresponding electrical signals that are fed back to the control module. The control module uses this signal to determine the duration of the suction head assembly's adhesion to the skin. If the duration of adhesion reaches a preset time, the control module stops drawing air from the suction head assembly and opens the air valve to draw in atmospheric air to achieve a rapid balance of air pressure inside and outside the suction head assembly. This prevents the suction head assembly from adhering to the skin and avoids causing damage to the skin.
