For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] Please refer to Figures 1 to 8, the present invention provides a technical solution: a non-contact button device for all-weather outdoor use, including a control box, which is composed of a non-contact induction button module, a function module, and a control panel. The non-contact induction button module is used to receive non-contact operation instructions from users, and has the characteristics of waterproof and dustproof, and can adapt to harsh outdoor weather. The non-contact induction button module is screwed to the control panel to receive non-contact operation instructions from users. The control box is installed in a suitable position on the pet stroller for convenient operation by users. The control panel is connected to each function module to control its operation.

[0020] The function module includes a heating module: when the user issues a heating instruction through the non-contact induction button module, the heating module starts to work to provide a warm environment for the pet in cold weather; the power of the heating module can be adjusted according to different needs to reach a suitable temperature.

[0021] A deodorizing and sterilizing module: when the deodorizing instruction is triggered, the deodorizing module effectively removes the odor inside the pet stroller, keeps the air fresh, and creates a comfortable environment for the pet and the user.

[0022] A ventilation module: adjusts the ventilation volume according to the user's instruction to ensure the air circulation inside the pet stroller. Especially in hot weather, it provides cool air for the pet to prevent the pet from suffering heat stroke.

[0023] A lighting module: controls the internal lighting to provide illumination for the pet to facilitate the pet's activities inside the stroller; the external lighting plays a warning role. For example, when traveling at night, it allows pedestrians and vehicles around to notice the presence of the pet stroller in time, improving safety.

[0024] The control panel is provided with switches, ventilation, heating, sterilization, and lighting buttons, and an indicator light with a corresponding pattern is set above each button. The working status of each function module is displayed through the indicator light. Users can easily operate on the control panel through the non-contact induction button module to select to turn on or off each function, and adjust the intensity of the function, such as heating temperature, ventilation volume, etc.

[0025] The surface of the control panel is sewn with elastic soft rubber 2 and nylon cloth 1. A flexible silicone waterproof layer 3 is also provided above the elastic soft rubber 2. The non-contact induction button module located inside the control panel corresponds to the flexible silicone waterproof layer 3, realizing internal and external isolation, waterproof and dustproof, and ensuring the stability and reliability of the circuit components 4 during product use. The non-contact induction button module includes a circuit board 6. A welding point 7 is provided in the center of the circuit board 6. Symmetrical circuit components 4 are provided on both sides of the welding point 7. A metal spring 8 is provided on the welding point 7. The metal spring 8 corresponds to the elastic soft rubber 2 above, as Figure 7 shown, is a schematic diagram of an existing contact pressing button, asFigure 8 As shown, it is a non-contact pressing button, and its improvements are as follows: In the gap between the silicone panel and the internal structural component, Figure 8 A metal spring 8 is used to replace the solid-state button switch. When the thickness of the silicone panel is greater than a few millimeters, the sensitivity of the metal spring 8 is much better than that of the standard solid-state button; due to the use of the capacitance detection principle, it can be used all-weather, such as in cold outdoors and rainy days. At the same time, using the metal spring 8 has the following advantages: A gap is provided between the circuit board 6 and the cover layer, which can keep different distances between the installed button and the panel, so as to facilitate supporting the cover layer wrapped by the nylon cloth 1; due to the elasticity of the metal spring 8, it can provide a reliable button sensing function when there is vibration or the distance between the cover layer and the board changes (such as when the trolley shakes).

[0026] It is very suitable for relatively thick cover layers, facilitating the design of the backlight of the front panel of the button sensor and further improving the user interface.

[0027] Inductive buttons usually require backlighting. Using the metal spring 8 as the button sensor can conveniently place LEDs inside for unified front panel lighting, thus achieving various types of backlighting. Installing the LEDs at the upper part of the circuit board 6 can provide a diffused backlight effect, and installing the LEDs at the lower part of the control panel can emit light upward through the opening to achieve a spotlight effect. The scattered light within a certain range is suitable for the backlight design of the icons on the control panel. The panel pattern, button size, and shape can be custom-designed, with a beautiful, fashionable, and technological appearance, presenting various functions to the user.

[0028] The capacitance principle involved is as follows: As Figure 5 shown, there is capacitance between any two conductive objects. The size of the capacitance is related to the conductive properties of the medium, the size of the electrode plates, and whether there is a conductive substance around the electrode plates, etc.

[0029] The change in touch capacitance is as Figure 6 shown. The large-area pads (inductive buttons) on the circuit board 6 and the nearby ground form a distributed capacitance; due to the existence of the human body capacitance, when a finger is above the electrode plate, the human body capacitance is combined with the distributed capacitance, resulting in an increase in the total capacitance and causing a change in capacitance.

[0030] Under the condition that the surrounding environment remains unchanged, the induced capacitance value is a fixed and tiny value; the user's finger only needs to be 1-3 millimeters away from the physical button without touching the induction button on the control panel, and it can be sensed. This makes the induced capacitance formed by the human finger and the ground in parallel with the induced capacitance formed by the induction button and the ground, which will increase the total induced capacitance value. The MCU touch port of the circuit processor is used to detect whether the induced capacitance value of a certain button has changed to determine whether a certain button has been pressed; if the corresponding button information is detected, the corresponding scenario can be entered to control modules such as the fan, heating, and sterilization to work according to the preset logic.

[0031] As Figure 3 described above, the control box can be connected to each functional module on the pet stroller through wires, such as the heating module, deodorization and sterilization module, ventilation module, and lighting module, to provide a comfortable and safe moving environment for the pet.

[0032] Operation process: When the user approaches the non-contact induction button module, when the operation intention of the user is sensed, the non-contact induction button module transmits the signal to the control panel. According to the key value judgment, if there is no button press within 15 minutes, it enters the standby mode.

[0033] If a function button is recognized, for example, when the user turns on the heating function and selects the heating function option on the control panel, after the control panel receives the instruction, it transmits the instruction to the heating module, and the heating module starts to work and heats according to the preset temperature parameters.

[0034] Similarly, for the deodorization and sterilization, ventilation, and lighting functions, the user can also control them on the control panel through a similar operation process; during the operation of the functions, the control panel monitors the working status of each functional module in real time and displays relevant information on the operation interface, such as the heating temperature, ventilation volume, deodorization status, and lighting brightness.

[0035] The device embodiments described above are only illustrative. The units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed to multiple network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment. Those of ordinary skill in the art can understand and implement it without creative labor.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
