Description

Technical Field

[0001] This utility model relates to the technical field of eye massagers, and more particularly to an eye massager that uses a piezoelectric pump. Background Technology

[0002] Eye massagers come in various types, mainly including airbag massagers, vibration massagers, and heat therapy massagers. Airbag massagers, in particular, use the inflation and deflation of airbags to simulate fingertip kneading techniques, gently pressing on the muscles and acupoints around the eyes to promote blood circulation and relieve eye fatigue. In airbag massagers, the airbags are typically inflated and expanded by an air pump. However, existing ordinary air pumps often use motors to drive pistons or impellers to generate airflow. This operation and the friction and collision between components produce significant noise and wear, resulting in a shorter lifespan and impacting the user experience. Furthermore, ordinary air pumps have complex structures, are bulky and heavy, hindering the miniaturization and portability of eye massagers. Additionally, ordinary air pumps struggle to achieve precise and independent control of multiple airbags, affecting the accuracy and personalization of the massage.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This invention addresses the problems of conventional air pumps in existing eye massagers, such as high noise levels, short lifespan, large size, poor portability, and insufficient massage precision. It proposes an eye massager that uses a piezoelectric pump.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

The air inlet pipe is used to input gas into the air chamber, the outlet pipe is connected to the air inlet end of the control valve, and the air outlet end of the control valve is connected to the airbag massage mechanism.

[0013] As described above, an eye massager using a piezoelectric pump includes an airbag massage mechanism comprising an airbag module located on the outside of the rear housing, wherein the airbag interface of the airbag module can extend into the massage housing and connect to the piezoelectric pump device.

[0014] As described above, in an eye massager employing a piezoelectric pump, the airbag module includes at least a first airbag, which is used to cover at least the eye area.

[0015] As described above, in an eye massager employing a piezoelectric pump, the airbag module includes at least a first airbag, which is used to cover the temple area, and the first airbag is provided at both ends of the massage housing.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention relates to an eye massager that utilizes a piezoelectric pump instead of a conventional air pump. The piezoelectric pump is small and lightweight, making it easy to integrate into the eye massager without making it too large or heavy, thus facilitating user portability and use. The piezoelectric pump precisely controls the gas flow and pressure, allowing for precise adjustment of the inflation and deflation of each airbag according to different massage needs, such as massage intensity and mode.

It also generates minimal noise and vibration during operation, creating a quiet and comfortable massage environment for users, making it easier for them to relax. In addition, the piezoelectric pump has high energy conversion efficiency, resulting in lower energy consumption for the same massage effect, thus reducing the power consumption of the eye massager, extending its usage time, and improving its overall performance and economy.

The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

If the specific posture changes, the directional indicator will also change accordingly.

[0038] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0039] like Figure 1As shown in Figure 12, this utility model provides an eye massager using a piezoelectric pump, including a massage housing 1, an airbag massage mechanism, and a piezoelectric pump device 4. The massage housing 1 includes a front housing 11 and a rear housing 12 arranged opposite to each other. The rear housing 12 is used to cover at least the eye area S1, that is, the rear housing 12 can also be used to cover the eye area S1 and the temple area S2. The airbag massage mechanism is disposed between the front housing 11 and the rear housing 12. The piezoelectric pump device 4 is connected to the airbag massage mechanism, and drives the airbag massage mechanism to generate a massage action, thereby realizing the massage effect through the airbag. The piezoelectric pump device 4 massages the human body. In practical applications, the piezoelectric pump device 4 utilizes the inverse piezoelectric effect of piezoelectric materials. When an electric field is applied to the piezoelectric material, it undergoes mechanical deformation, thereby driving a change in the volume of the pump chamber. When the piezoelectric pump device 4 is used in conjunction with the airbag massage mechanism, the piezoelectric pump device 4 is connected to the airbag in the airbag massage mechanism. When the piezoelectric pump device 4 is working, its pump chamber volume increases, drawing in and storing gas. Subsequently, the pump chamber volume decreases, forcing the gas into the airbag, causing the airbag to expand and produce a squeezing massage effect on the human body. Afterward, the piezoelectric pump device 4 draws in gas again, the airbag deflates and contracts, and this cycle repeats to achieve the massage of the human body.

[0040] In this eye massager, a piezoelectric pump 4 replaces a conventional air pump. The piezoelectric pump 4 is small and lightweight, making it easy to integrate into the eye massager without making it too large or heavy, thus facilitating user portability and use. The piezoelectric pump 4 can precisely control the flow and pressure of the gas, accurately adjusting the inflation and deflation of each airbag according to different massage needs, such as massage intensity and mode, making the massage intensity and frequency more personalized to the user's individual needs, thereby optimizing the user experience. Furthermore, since the piezoelectric pump 4 has no mechanical friction parts, it experiences less wear and has a relatively long service life, reducing maintenance and replacement costs and improving the reliability and stability of the device. It also generates minimal noise and vibration during operation, creating a quiet and comfortable massage environment for users, making it easier for them to relax during the massage. In addition, the piezoelectric pump 4 has high energy conversion efficiency, resulting in relatively low energy consumption for the same massage effect, which helps reduce the power consumption of the eye massager, extend its usage time, and improve the overall performance and economy of the device.

[0041] Specifically, such as Figure 3As shown, the piezoelectric pump device 4 is disposed between the front housing 11 and the rear housing 12, forming an inner cavity of the massage housing 1 between the front housing 11 and the rear housing 12 to accommodate the piezoelectric pump device 4. The piezoelectric pump device 4 includes an electronic control module, a piezoelectric pump electrically connected to the electronic control module, and a control valve. The electronic control module can supply power to the piezoelectric pump and control the piezoelectric pump and the control valve. The electronic control module can be integrated into the control system of the eye massager, or it can be set independently of the original control system of the eye massager. When the electronic control module is set as an independent module, it is electrically connected to the control system in the eye massager. The electronic control module can also be a universal electronic control module applicable to various types and brands of eye massagers. In addition, in this embodiment, the piezoelectric pump device 4 can be a common small or micro piezoelectric pump integrated device. The piezoelectric pump device 4 is detachably fixed between the front housing 11 and the rear housing 12. For example, the piezoelectric pump device 4 can be installed inside the front housing 11 or the rear housing 12 by fasteners such as screws and bolts, or installed between the front housing 11 and the rear housing 12 by an additional connecting bracket.

[0042] Furthermore, the piezoelectric pump has an internal air chamber, and an air inlet pipe and an air outlet pipe connected to the air chamber are located on the outside of the piezoelectric pump. The air inlet pipe is used to input gas into the air chamber, and the air outlet pipe is connected to the air inlet end of the control valve. The air outlet end of the control valve is connected to the airbag massage mechanism. Specifically, the air inlet pipe can be connected to the external environment through an air inlet valve. The air inlet pipe absorbs gas through the air inlet valve and inputs gas into the air chamber. When the piezoelectric element of the piezoelectric pump vibrates under the action of an alternating electric field, the volume of the air chamber will change periodically. During the stage of increasing air chamber volume, the pressure inside the air chamber decreases, forming a negative pressure. At this time, the air intake valve opens under the action of pressure difference, and the outside gas enters the air chamber through the air intake valve under the action of atmospheric pressure; when the volume of the air chamber decreases, the pressure inside the air chamber increases, the air intake valve closes to prevent gas backflow, and at the same time the gas is compressed and discharged into the air bladder in the air bladder massage mechanism through the control valve, so that the air bladder undergoes elastic deformation and produces a massage action, thereby realizing the massage of the human body parts.

[0043] Furthermore, the control valve is connected to the airbag in the airbag massage mechanism via a pipeline, and controls the gas flow direction and gas flow rate through the control valve; the number of the piezoelectric pump and the control valve can be set comprehensively based on the size and number of airbags in the airbag massage mechanism; for example, when there are many airbags, in order to ensure that each airbag can be inflated and deflated quickly and accurately, the number of piezoelectric pumps and air valves may be increased; taking an eye massager with 4 airbags as an example, if it is desired to achieve independent and precise massage control for each airbag, 4 air valves can be configured, while the piezoelectric pump can be configured with 1 or 2 depending on factors such as the inflation speed requirements of the airbags.

[0044] In some alternative embodiments, when a single piezoelectric pump is equipped with a large number of air bladders, an intermediate air chamber can be set inside the piezoelectric pump. This intermediate air chamber can serve as a pressure buffer area, storing a certain amount of gas. The gas in the intermediate air chamber can play a supplementary or buffering role, so as to facilitate stable output, buffering and shock absorption, improve gas transmission efficiency, and optimize gas flow control when the piezoelectric pump is working.

[0045] Specifically, the piezoelectric pump device 4 also includes a pressure sensor to detect the pressure in the air chamber. The pressure sensor can monitor the gas pressure output by the piezoelectric pump in real time, converting the pressure signal into an electrical signal and feeding it back to the electronic control module. This allows the user to understand the operating status of the piezoelectric pump, such as whether the pressure is stable or has reached the set value, thus protecting and precisely controlling the piezoelectric pump, thereby improving the massage effect and optimizing the user experience. Optionally, the pressure sensor can be directly installed in the air outlet pipe and the air chamber of the piezoelectric pump; or, the pressure sensor can be connected to the air outlet pipe of the piezoelectric pump via an adapter.

[0046] like Figure 1 As shown in Figure 6, the airbag massage mechanism includes an airbag module 21, which is located on the outside of the rear housing 12. The airbag interface 22 of the airbag module 21 can extend into the massage housing 1 and connect to the piezoelectric pump device 4. The airbag module 21 may be provided with one or more airbags of different volumes. Each airbag has an airbag interface 22 on one side, and each airbag can be connected to the rear housing 12 through a connecting component.

[0047] In some optional embodiments, the connecting assembly includes a flexible suspension sleeve 312 connected to the rear housing 12, a fixing bracket 313 disposed between the flexible suspension sleeve 312 and the airbag, a supporting base plate 33 disposed between the fixing bracket 313 and the airbag, and the flexible suspension sleeve 312, the fixing bracket 313 and the supporting base plate 33 having a through hole through which the airbag interface 22 can pass; the flexible suspension sleeve 312 has a first mounting portion 3121 for connecting to the rear housing 12 and a second mounting portion 3122 located on one side of the first mounting portion 3121, the second mounting portion 3122 being used to mount the fixing bracket 313; the outer side of the rear housing 12 has a mounting port 121 communicating with the inner cavity of the massage housing 1, and a supporting cylinder 122 disposed outside the mounting port 121 and extending away from the rear housing 12, the first mounting portion 3121 being able to extend through the mounting port 121. The airbag is inserted into the inner cavity of the massage housing 1 and snapped into the mounting port 121. The flexible suspension sleeve 312 is reinforced and fixed in the rear housing 12 by the support cylinder 122. The flexible suspension sleeve 312 has a second mounting part 3122 on the side away from the first mounting part 3121. The flexible suspension sleeve 312 has a mounting groove 3123. The fixing bracket 313 is snapped into the mounting groove 3123 through the second mounting part 3122, and the fixing bracket 313 is adapted to the mounting groove 3123. The support base plate 33 is snapped into one side of the fixing bracket 313. The airbag can be fixedly installed in the side of the support base plate 33 facing the human body by means of adhesive or other methods. The airbag interface 22 can extend into the inner cavity of the massage housing 1 through the through hole and be connected to the piezoelectric pump device 4 through the pipeline, thereby realizing the connection of the airbag to the rear housing 12. The structure is simple and easy to assemble.

[0048] On the other hand, the airbag configuration in the airbag module 21 can have multiple schemes, as detailed below.

[0049] like Figure 7 As shown, one specific embodiment of the airbag configuration in the airbag module 21 is that the airbag module 21 includes at least a first airbag 21a, which is used to cover the eye area S1; or, as shown...

The massage housing 1 is provided with the first airbag 21a at both ends. The eye massager may also be provided with other types of massage mechanisms applied to the eye area S1, such as vibration massage, steam hot compress massage, etc.

[0051] like Figure 10 As shown, a third specific embodiment of the airbag configuration in the airbag module 21 is that the airbag module 21 includes a first small airbag 211a and a second small airbag 212a, wherein the first small airbag 211a and the second small airbag 212a may be of equal size, and the first small airbag 211a and the second small airbag 212a are smaller than the first airbag 21a. The first small airbag 211a is used to cover the left eye area, and the second small airbag 212a is used to cover the right eye area; or, as shown...

Each of the third small airbags 213a in the left airbag group H1 is distributed at intervals along a first arc path L1, and each of the third small airbags 213a in the right airbag group H2 is distributed at intervals along a second arc path L2. The first arc path L1 and the second arc path L2 can be combined to form an ellipse.

[0053] like Figure 13 As shown, one of the specific implementations of the airbag configuration in the airbag module 21 is that the airbag module 21 includes a first airbag 21a, a second airbag 21b and a third airbag 21c. The first airbag 21a is used to cover the eye area S1, the second airbag 21b is used to cover the left temple area, and the third airbag 21c is used to cover the right temple area.
