[0086] Preferably, a pressure sensor is disposed on the lifting seat plate, the pressure sensor is located between the lifting seat plate and the detachable seat cushion (12), and the pressure sensor is connected to a signal converter via a data line;
[0087] The signal converter can convert the electrical signal of the pressure data collected by the pressure sensor into a digital signal.
[0088] The controller may be implemented by one or at least two application specific integrated circuits (ASICs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components for executing instructions of the data processing device.
[0089] The data processor and the signal converter perform information exchange, and a computer-readable storage medium is stored in the data processor, and the following steps are implemented when the computer-readable storage medium is executed:
[0090] After receiving the pressure data transmitted by the signal converter, the pressure data is processed and the pressure data is compared with a preset threshold value. If the pressure data is less than the preset threshold value, it means that no one is using the wheelchair, and a command is sent to the controller, and the controller controls the ultraviolet sterilization lamp (4) to turn on to disinfect the wheelchair; if the pressure data is greater than the preset threshold value, it means that someone is using the wheelchair, and a command is sent to the controller, and the controller controls the ultraviolet sterilization lamp (4) to turn off;
[0091] When in use, the patient sits on the lifting seat board. If the height needs to be adjusted, the control button on the wheelchair armrest (13) is used to control the electric lifting rod (16) to extend or retract. The electric lifting rod (16) drives the lifting seat board to rise or fall. At the same time, the leg support plate (10) and the wheelchair backrest (2) rise or fall with the lifting seat board and are adjusted to a height that the patient feels comfortable. During the lifting process, the lifting limit rod (15) rises or falls with the lifting seat board. The limit plate (18) slides in the lifting limit cylinder (14) to limit the lifting limit rod (15), thereby limiting the lifting seat board, so that the lifting or falling of the lifting seat board is more stable. At the same time, the pressure sensor senses The pressure signal received is continuously transmitted to the signal converter, and the signal converter converts the electrical signal of the pressure data collected by the pressure sensor into a digital signal and transmits it to the data processor. After receiving the pressure data transmitted by the signal converter, the data processor processes the pressure data and compares the pressure data with a preset threshold value. If the pressure data is less than the preset threshold value, it means that no one is using the wheelchair, and an instruction is sent to the controller, and the controller controls the ultraviolet sterilization lamp (4) to turn on to disinfect the wheelchair; if the pressure data is greater than the preset threshold value, it means that someone is using the wheelchair, and an instruction is sent to the controller, and the controller controls the ultraviolet sterilization lamp (4) to turn off; Example 2
[0092] The difference between this embodiment and the first embodiment is that: the lifting seat plate is provided with a plurality of ventilation holes (19), the detachable seat cushion (12) is provided with a plurality of ventilation holes (19), and the plurality of ventilation holes (19) on the lifting seat plate and the plurality of ventilation holes (19) on the detachable seat cushion (12) correspond one to one; when in use, the ventilation holes (19) form ventilation passages, which can effectively reduce the accumulation of heat and moisture, keep the wheelchair dry, reduce bacterial growth, and reduce the risk of cross infection when used for a long time or in a relatively hot environment; Example 3
[0093] The difference between this embodiment and embodiment 1 is that: a support cushion (20) is disposed on the leg support plate (10), one side of the support cushion (20) is detachably connected to the leg support plate (10), and the other side of the support cushion (20) is an arc-shaped structure, and the support cushion (20) is preferably a sterilization cushion; when in use, it can fit the patient's leg curve, reduce leg pressure, help the patient avoid leg fatigue and discomfort, and facilitate cleaning and replacement, and the sterilization cushion reduces the risk of cross infection;
[0094] The lifting limit cylinder (14) cooperates with the limit ring to limit the limit plate (18), and the limit plate (18) slides in the lifting limit cylinder (14) to limit the lifting limit rod (15), thereby limiting the lifting seat plate, so that the lifting seat plate can be raised or lowered more stably;
[0095] The design that the inner diameter of the stop ring opening is smaller than the inner diameter of the lifting stop cylinder (14) can constrain the stop plate (18) during the lifting process, thereby preventing the stop plate (18) from sliding out of the lifting stop cylinder (14) during the lifting process, thereby causing deviation in the lifting action of the lifting seat plate and affecting the lifting stability;
[0096] The design of the ultraviolet sterilization lamp (4) being higher than the height of the lifting seat plate can ensure that the ultraviolet rays can effectively irradiate the upper surface of the lifting seat plate and the entire area of the wheelchair backrest (2), thereby performing a relatively comprehensive disinfection and sterilization treatment on the wheelchair, and effectively reducing the risk of cross infection;
[0097] The electric lifting rod (16) can be used to drive the lifting seat to automatically rise and fall, so as to meet the needs of different heights. At the same time, the ultraviolet sterilization lamp (4) can be used to automatically disinfect and sterilize the wheelchair when no one is using it, so as to avoid cross infection when multiple people use it.
[0098] It should be noted that, unless otherwise clearly specified and limited, the terms "placed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection method such as a folding connection, a rivet connection, a pin connection, a bonding connection and a welding connection, or a detachable connection method such as a threaded connection, a snap connection and a hinge connection, or an integral connection, or an electrical connection, or a direct connection, or an indirect connection through an intermediate medium, or the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0099] It should be further pointed out that, when describing the above specific embodiments, for the sake of simplicity and clarity, only the differences between the above specific embodiments are described, but those skilled in the art should know that the above specific embodiments themselves are also independent technical solutions.
[0100] It should be noted that the terms “front”, “rear”, “left” and “right” in this utility model are used in conjunction with the attached Figure 1 The “front”, “back”, “left” and “right” in the text shall prevail.
