Description

Technical Field

[0001] The utility model relates to adult products, in particular to an adult product comprising a pressure sensor. Background Art

[0002] With the advancement of technology and the improvement of living standards, users of adult products have gradually increased their demands for comfort and convenience. Existing adult products usually require users to try different working powers and then make adjustments. The user experience of end customers still needs to be further optimized and improved. Utility Model Content

[0003] The purpose of the utility model is to provide an adult product with higher convenience.

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] A pressure sensor, comprising:

[0006] A flexible substrate, wherein the flexible substrate is configured to include a plurality of sensing areas and a plurality of connection areas, and adjacent sensing areas are connected via the connection areas;

[0007] The pressure-sensitive layer is formed on the flexible substrate, and includes a plurality of pressure-sensitive points formed in the sensing area and a plurality of connecting lines, each of the pressure-sensitive points is connected to the detection circuit through the connecting line, and each of the connecting areas is constructed into a strip structure adapted to the connecting line.

[0008] Optionally, each of the sensing areas is formed with a plurality of the pressure-sensitive points.

[0009] Optionally, the pressure-sensitive points are connected in parallel via the connecting lines.

[0010] Optionally, the pressure-sensitive points are connected in an array manner via the connecting lines.

[0011] Optionally, each of the sensing areas is configured as a shuttle-shaped structure.

[0012] Optionally, a flexible packaging layer is further included, and the pressure-sensitive layer is packaged between the flexible substrate and the packaging layer.

[0013] Optionally, the pressure-sensitive point includes a conductive film and an electrode separated from each other, and the conductive film is deformed toward the electrode when subjected to pressure, so that the resistance value of the pressure-sensitive point changes with the pressure applied to the conductive film.

[0014] Optionally, an adhesive layer is provided on a side of the flexible substrate away from the pressure-sensitive layer.

[0015] In a second aspect, the utility model further provides an adult product, comprising an inner shell, the above-mentioned pressure sensor and a motor, wherein the motor is accommodated inside the inner shell and vibrates controllably, and the sensor is arranged on the outer wall of the inner shell.

[0016] Optionally, it further includes a flexible shell, the sensor is electrically connected to the motor, and the flexible shell is sleeved on the outside of the inner shell.

[0017] According to the first aspect of the utility model, by setting up a plurality of mutually separated sensing areas, it is convenient for each sensing area to fit with the curved surface to be measured, thereby fixing the spatial position of each sensing area, ensuring that the pressure between the pressure-sensitive layer and each sensing area is the pressure exerted on the curved surface, preventing measurement errors caused by gaps between the sensing areas and the curved surface, and helping to improve the accuracy of the measured values.

[0018] Furthermore, since the connection part is a strip structure, the strength and rigidity are both low, and it is easy to deform and damage. By integrating multiple pressure-sensitive points in the same sensing area and reducing the number of connection parts, it helps to improve the integrity of the pressure sensor, reduce the risk of damage, and prevent the overall deformation of the pressure sensor due to deformation of the connection part, which facilitates the positioning and setting of the pressure sensor as a whole and helps to locate each pressure-sensitive point.

[0019] Furthermore, the pressure-sensitive points are connected in parallel and only the maximum pressure value is detected, so that the demand can be achieved with a simple circuit, which helps to reduce costs and simplify the structure.

[0020] Furthermore, by connecting the pressure-sensitive points in an array, the pressure value of each pressure-sensitive point can be detected, which helps to expand the application range of the pressure sensor.

[0021] Furthermore, constructing the sensing area into a shuttle-shaped structure helps to make the sensing area fit the curved surface better.

[0022] Furthermore, a pair of electrodes are separated from each other and connected to the two poles of the power supply respectively. Since the conductive diaphragm and the two poles of the electrode are not in contact with each other, the resistance at the pressure-sensitive point is infinite. When the conductive diaphragm is subjected to force, it deforms, causing part of the conductive diaphragm to contact the two poles of the electrode at the same time, so that the circuit is connected. The greater the force on the conductive diaphragm, the greater the deformation, the larger the contact area with the electrode, and the smaller the resistance at the pressure-sensitive point. By detecting the change in resistance, the change in pressure value can be detected, which is low-cost and suitable for environments with small pressure thresholds.

[0023] Furthermore, the packaging layer is provided to protect the internal structure of the pressure sensor, so that the surface of the pressure sensor is easy to clean.

[0024] Furthermore, by providing an adhesive layer, it is easier to install the pressure sensor, thereby improving convenience.

[0025] According to the second aspect of the utility model, by arranging a pressure sensor on the housing of the adult product, the pressure exerted by the human body on the adult product can be effectively detected, which is convenient for setting the power of the motor.

[0026] Furthermore, by electrically connecting the pressure sensor to the motor, the power of the motor can be adjusted sensitively and automatically, thereby improving convenience during use and optimizing the user experience.

[0027] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

[0032] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] See also Figure 1 , Figure 2 and Figure 3 The pressure sensor 1 protected by the utility model application includes a flexible substrate 11 and a pressure-sensitive layer 12 formed on the flexible substrate 11. The flexible substrate 11 is configured to include a plurality of regions, including a plurality of sensing regions 111 and a plurality of strip-shaped connecting regions 112 connecting adjacent sensing regions 111. The pressure-sensitive layer 12 includes a plurality of pressure-sensitive points 121, and each of the pressure-sensitive points 121 is formed in the sensing region 111 of the flexible substrate 11 and connected to the detection circuit via a connecting line 125.

[0037] By using the flexible substrate 11, the pressure sensor 1 can be arranged on a structure different from the initial shape of the flexible substrate 11. By setting a plurality of sensing areas 111, the flexible substrate 11 can be prevented from being too large and difficult to fit with the curved surface structure. By setting the connection area 112 between adjacent sensing areas 111, it is helpful to improve the integrity of the pressure sensor 1, facilitate the setting of the pressure sensor 1, and prevent the pressure sensor 1 from being deformed after being arranged on the curved surface, resulting in deviations in the positions of the pressure sensitive points 121. The connection area 112 is arranged in a strip shape, which can reduce costs and improve fit.

[0038] Embodiment 1:

[0039] See also Figure 1 , Figure 2and Figure 3 The adult product shown in a preferred embodiment of the present application includes a pressure sensor 1, a main board (not shown) and an inner shell 2. The main board is fixedly connected to the inner shell 2, and the pressure sensor 1 is attached to the outer wall of the outer shell and connected to the main board.

[0040] The cross section of the inner shell 2 in this embodiment is a rounded triangle, and the outer wall is a smooth curved structure. The surface of the inner shell 2 is provided with a plurality of sets of opposite screw holes 21 for fixing the mainboard. The side with the shortest side of the triangle is the second end 23 of the inner shell 2, and the position opposite to the bottom is the first end 22 of the inner shell 2. In other embodiments, the cross section of the inner shell 2 may be in other shapes, such as a circle, an ellipse or a strip.

[0041] The pressure sensor 1 includes a flexible substrate 11, a pressure-sensitive layer 12 and a flexible packaging layer 13. The pressure-sensitive layer 12 is formed on one side of the flexible substrate 11, and the shape of the flexible packaging layer 13 is adapted to the pressure-sensitive layer 12 and connected to the edge of the pressure-sensitive layer 12, so that the pressure-sensitive layer 12 is encapsulated between the flexible substrate 11 and the flexible packaging layer 13.

[0042] In this embodiment, the flexible substrate 11 is made of polyethylene terephthalate (PET), which has the advantage of maintaining excellent electrical insulation at high temperature and high frequency, and has good creep resistance, fatigue resistance, friction resistance, and dimensional stability, can be attached to the outer wall of the inner shell 2, and can provide good protection for the pressure-sensitive layer 12. In other embodiments, the flexible substrate 11 can also be made of other films with good electrical insulation, such as non-woven fabrics.

[0043] The flexible substrate 11 includes a plurality of sensing areas 111, a plurality of connection areas 112 and an output area 113. In this embodiment, four shuttle-shaped sensing areas 111 are included, and the four sensing areas 111 are arranged in a direction from the first end 22 to the second end 23 of the inner shell 2. A long strip-shaped connection area 112 is connected between adjacent sensing areas 111, and a strip-shaped output area 113 is connected to the side of the sensing area 111 adjacent to the second end 23 of the inner shell 2 near the second end of the inner shell 2. Constructing the sensing area 111 in a shuttle shape helps to ensure that the sensing area 111 covers a large area of ​​the outer wall of the outer shell while fitting with the outer wall of the inner shell 2, and helps to maintain the integrity and stability of the overall shape of the pressure sensor 1 and the relative positional relationship between the sensing areas 111. Constructing the connection area 112 in a strip shape helps to fit with the outer wall of the inner shell 2.

[0044] The pressure-sensitive layer 12 includes a plurality of pressure-sensitive points 121 for detecting the pressure at the location. The pressure-sensitive point 121 includes an electrode 122, an isolation layer 123 and a conductive diaphragm 124. The electrode 122 is connected to the flexible substrate 11, and the isolation layer 123 is made of insulating material and is arranged on the side of the electrode 122 away from the flexible substrate 11, and the center thereof is hollowed out. The conductive diaphragm 124 is elastic and connected to the isolation layer 123 so that the conductive diaphragm 124 does not contact the electrode 122. In this embodiment, each sensing area 111 of the flexible substrate 11 is formed with three sensing points, which is helpful to collect the pressure at specific locations respectively. The conductive diaphragm 124 includes an insulating thin film layer 1241 and a conductive layer 1242 covering the surface of the thin film layer, and the conductive layer 1242 is arranged on the side of the thin film layer 1241 close to the electrode 122.

[0045] In this embodiment, the electrode 122 adopts a forked electrode. The forked electrodes arranged in the same sensing area 111 are connected to each other to form a pair of integral forked electrodes. The two poles of the forked electrodes are respectively connected to the connecting line 125, so that each pressure-sensitive point 121 arranged in the same sensing area 111 is connected in parallel. The connecting line 125 extends from the connecting area 112 to the adjacent sensing area 111 and connects with another pair of forked electrodes, and then continues to extend to the output area 113, and connects to the terminal 126 at the end of the output area 113, and is connected to the detection circuit through the terminal 126. In the initial state, since the conductive diaphragm 124 and the two poles of the forked electrodes are separated from each other, a circuit is formed between the two connecting lines 125. When the conductive diaphragm 124 is subjected to pressure in the direction of the electrode 122, the conductive diaphragm 124 is deformed to contact the two poles of the electrode 122 at the same time, and the circuit is connected at this time. With the change of pressure, the resistance of the pressure-sensitive point 121 changes. Since the pressure-sensitive points 121 are connected in parallel, the detection circuit can only detect the pressure value of the pressure-sensitive point 121 that is subjected to the maximum pressure. In this embodiment, the isolation layer 123 is made of adhesive, and the conductive diaphragm 124 is made of a circular PET film with a graphite coating on the surface. In other embodiments, the film layer 1241 can also be made of other flexible films with good dimensional stability and electrical insulation, such as polyvinyl alcohol (PVA), polyimide (PI), polyethylene naphthalate (PEN) or any one of textile materials; the conductive layer 1242 can also be made of other powdered substances with good conductivity and easy to coat, such as one or more of carbon powder, carbon nanotubes, and graphene.

[0046] The shape of the flexible encapsulation layer 13 is adapted to the shape of the flexible substrate 11 and covers the pressure-sensitive layer 12. The edge of the flexible encapsulation layer 13 is connected to the edge of the flexible substrate 11 to protect the pressure-sensitive layer 12. In this embodiment, the flexible encapsulation layer 13 is made of PT film material and is encapsulated by heat sealing.

[0047] The pressure sensor 1 further includes an adhesive layer 14 , which is disposed on a side of the flexible substrate 11 away from the pressure-sensitive layer 12 and is made of a pressure-sensitive adhesive material for adhering the pressure sensor 1 to the outer wall of the inner shell 2 .

[0048] The main board includes a fixing plate (not shown), a motor (not shown) and a controller (not shown), and the fixing plate is fixedly connected to the inside of the inner shell 2 through the screw hole 21 on the inner shell 2. The motor and the control module are fixed to the fixing plate. The control module includes a detection circuit, and the connection area 112 of the pressure sensor 1 is bent toward the inside of the inner shell 2, passes through the inner shell 2 and is connected to the detection circuit. The motor is electrically connected to the controller. In this embodiment, the motor adopts a button-type vibration motor and has multiple power gears, which can controllably drive the inner shell 2 to vibrate under the action of the controller.

[0049] The adult product also includes a flexible outer shell (not shown), which is wrapped around the inner shell 2 and the outer side of the pressure sensor 1, is easy to clean, and improves the safety of use.

[0050] The beneficial effect of the utility model is that by setting pressure-sensitive points 121 at each pressure-bearing part of the adult product, the changes in pressure at each pressure-bearing position are tracked, and the vibration power is independently adjusted according to the maximum pressure value, thereby improving the convenience of the product and enhancing the customer experience and satisfaction.

[0051] Embodiment 2:

[0052] The only difference between this embodiment and the first embodiment is that the encapsulation layer 13 is not included, and each pressure-sensitive point 121 is protected by a thin film layer, and the connecting wire 125 of the pressure-sensitive layer 12 is fixed to the flexible substrate 11 by an adhesive, which also plays a protective role.

[0053] Embodiment three:

[0054] The only difference between this embodiment and the first embodiment is that the pressure-sensitive points 121 are connected in an array through connecting lines 125 , so that the pressure values ​​of the pressure-sensitive points 121 are output respectively.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
