AI Technical Summary
Patients with poor self-care ability find it difficult to use a handheld fan to blow on their faces to relieve breathing difficulties. Conventional fans cannot blow on the face in a precise and targeted manner and can easily cause other parts of the body to get cold, leading to problems such as chills, affecting the patient's comfort and health.
An induction bracket fan is designed. The induction element on the facial carrier detects the dyspnea signal. The control chip sends a command to start the fan host to blow air in a directional manner toward the face. The fan host is connected to the bed with a stable clamp to prevent cold air from blowing to other parts of the body.
It can conveniently relieve breathing difficulties for patients with poor self-care ability. The cold air from the fan only acts on the face, which improves the user experience and treatment compliance and prevents other parts of the body from getting cold.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical auxiliary equipment, in particular to an induction type bracket fan. Background Art
[0002] Dyspnea, a common symptom that causes significant pain and can even lead to disability, has attracted considerable attention in clinical and daily care settings. Existing research clearly indicates that cooling air from a fan directed toward the face can effectively alleviate dyspnea. This is because the cold stimulation of the face regulates respiratory-related nerve reflexes, thereby alleviating the patient's feeling of suffocation. However, cold air applied to other parts of the body does not have this effect.
[0003] In practical applications, patients with adequate self-care abilities can use a handheld fan to blow on their faces to relieve discomfort. However, for those with limited self-care abilities, such as those suffering from paralysis, post-operative weakness, or the elderly, operating a handheld fan is nearly impossible, causing them to miss the opportunity to use a fan to alleviate their symptoms. Furthermore, conventional fans not only fail to accurately direct air toward the face, but can also easily chill other parts of the body, causing unnecessary chills and colds. This is extremely detrimental to maintaining a patient's physical condition and may even trigger other conditions such as colds and joint pain, increasing patient suffering and the burden on medical care. Utility Model Content
[0004] In order to solve the above problems, especially to address the deficiencies in the prior art, the utility model provides an induction bracket fan that can solve the above problems.
[0005] In order to achieve the above purpose, the utility model adopts the following technical means:
[0006] An induction-type bracket fan includes an induction component and a fan component. The induction component includes a face carrier, the inner side of the face carrier is connected to multiple groups of evenly distributed induction elements, the outer side of the face carrier is connected to an induction control box, the induction control box is internally connected to a control chip, a wireless transmission module, and a mobile power supply, the induction control box is externally connected to a control switch, the control chip is connected to the mobile power supply via the control switch, and the induction elements and the wireless transmission module are respectively electrically connected to the control chip;
[0007] The fan component includes a fan host, which is rotatably connected to a stabilizing clip, and is connected to a fan control box. A microprocessor, a wireless receiving module, and a power adapter are connected to the fan control box, and a speed control switch is connected to the outside of the fan control box. The fan host and the microprocessor are respectively connected to an external power supply through a power adapter, and the fan host, the wireless receiving module, and the speed control switch are respectively electrically connected to the microprocessor, and the wireless receiving module is wirelessly connected to the wireless sending module.
[0008] A further solution of the present invention is that the facial carrier is a mask.
[0009] A further solution of the present invention is that the sensing element is an infrared sensing element.
[0010] A further solution of the present invention is that the induction control box and the fan control box are both made of plastic.
[0011] A further solution of the present invention is that the control chip is an STM32F103 control chip.
[0012] A further solution of the present invention is that a signal processing module is connected between the sensing element and the control chip.

[0016] A further solution of the present invention is that the anti-slip pad is a rubber product.
[0017] Beneficial effects of the utility model:
[0018] 1. The sensing component of the utility model fits the patient's face. When the sensing component is activated and sends a start command to the fan component, the fan host responds quickly and starts blowing. The cold air blows directly to the key areas of the face, acting only on the face, preventing other parts of the body from being affected by the cold.
[0019] 2. The bracket fan of the utility model is placed independently and does not need to be held by the patient, which provides convenience for those with poor self-care ability, allowing them to continue to enjoy the relief effect of cold air flow, greatly improving the user experience and treatment compliance.
