[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by this utility model is to provide a blower that can automatically adjust the working mode and temperature according to the installation status of the nozzle and the distance between the object being tested and the air outlet, thereby improving the ease of use and making it safer.

[0005] (II) Technical Solution

[0006] The solution adopted by this utility model to solve the above-mentioned technical problems is a blower device, including...

[0007] A hair dryer includes an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet;

[0008] The nozzle is detachably connected to the air outlet of the blower unit;

[0009] A heating element is disposed within the air duct;

[0010] The first detection element is used to detect whether a nozzle is installed at the air outlet.

[0011] The second detection element is used to detect the distance between the object being tested and the air outlet.

[0012] The control unit is electrically connected to the first detection element and the second detection element, and is able to control the working state of the heating element according to the detection results.

[0013] Specifically, the air duct of the blower host has an L-shaped cross-section, and a filter, a fan assembly, and a heating element are sequentially arranged in the air duct from the air inlet end to the air outlet end; and the first detection element and the second detection element are located on the side of the blower host closer to the air outlet end, and the control unit is located on the side of the blower host away from the air outlet end, and is connected to the side of the heating element away from the air outlet end.

[0014] By adopting the above solution, the installation status and usage distance of the nozzle can be monitored in real time through the cooperation of the first and second detection elements. The control unit can intelligently adjust the working status of the heating element according to the detection results, which improves product safety, prevents the risk of burns caused by misoperation or improper use, and enhances the user experience.

[0015] In some embodiments, the control unit includes an intelligent mode in which;

[0016] When the first detection element detects that a nozzle is installed at the air outlet, and when the second detection element detects that the distance between the tested object and the air outlet is within a first preset range, the control unit controls the heating element to work; when the second detection element detects that the distance between the tested object and the air outlet exceeds the first preset range, the control unit controls the heating element to stop working.

[0017] When the first detection element detects that no nozzle is installed at the air outlet, and when the second detection element detects that the distance between the tested object and the air outlet is within a second preset range, the control unit controls the heating element to stop working; when the second detection element detects that the distance between the tested object and the air outlet exceeds the second preset range but is within a third preset range, the control unit controls the heating element to work; and the control unit can adjust the working power of the heating element according to the real-time distance between the tested object and the air outlet to achieve constant temperature operation; when the second detection element detects that the distance between the tested object and the air outlet exceeds the third preset range, the control unit controls the heating element to stop working.

[0018] Specifically, the control unit is equipped with multiple operating modes, including intelligent mode, high temperature setting, medium temperature setting, low temperature setting, and hot and cold cycle setting. Users can select the desired operating mode through control buttons; multiple control buttons are provided on the outer wall of the blower unit for selection.

[0019] By adopting the above solution and employing differentiated control logic in an intelligent mode, the device can intelligently adjust its heating state under different usage scenarios. When a nozzle is installed, it heats at close range and stops at a distance; when no nozzle is installed, it stops at close range to prevent burns; and it heats at a distance. This ensures both effective airflow and maximizes user safety, enhancing the product's intelligence. Furthermore, within a specific distance range without a nozzle, the device can dynamically adjust the heating power based on real-time distance to achieve a constant temperature, providing a more comfortable airflow experience, reducing overheating or underheating issues, saving energy, and extending the device's lifespan.

[0020] In some embodiments, the first preset range is 0-5cm; the second preset range is 0-2cm; and the third preset range is 2-22cm.

[0021] In some embodiments, the first detection element and the second detection element can operate independently.

[0022] Specifically, when the first detection element works independently, it turns on the heating element when the nozzle is installed and turns it off when it is not installed; or when the second detection element works independently, it turns on the heating element when the object being measured enters the effective distance range and turns it off when it exceeds the range.

[0023] In some embodiments, the control unit includes: a) an independent signal processing module for parsing the input of a single detection element; and b) a collaborative decision-making module for fusing the input signals of two detection elements.

[0024] In some embodiments, the second detection element includes an infrared distance sensor; and the second detection element is provided with an emitting micro-hole and a receiving micro-hole, and the upper end of the second detection element is provided with a beaming micro-hole device for beaming action.

[0025] By adopting the above scheme and using an infrared distance sensor as the second detection element, it is possible to measure distance accurately without contact. It has a fast response speed, is not affected by light, and can maintain good ranging performance in various operating environments, thus ensuring the reliability of intelligent control.

[0026] In some embodiments, the first detection unit includes a Hall effect sensor switch.

[0027] The above scheme uses a Hall effect sensor switch as the first detection element, which features high reliability, long lifespan, and strong anti-interference ability. It can accurately detect the installation status of the air nozzle and is not affected by environmental factors such as dust and moisture, thus improving the accuracy of detection and the durability of the equipment.

[0028] In some embodiments, the nozzle includes a first magnetic structure, and the blower host is provided with a second magnetic structure at the air outlet; the first magnetic structure and the second magnetic structure are arranged opposite to each other and can be magnetically connected; and the blower host is provided with the first detection unit near the second magnetic structure.

[0029] With the above solution, the nozzle and the blower unit are connected by magnetic attraction, which makes it easy for users to install and disassemble quickly and improves the ease of operation. At the same time, the magnetic attraction structure and the Hall effect sensor switch can accurately sense the installation status of the nozzle and ensure that the control logic is executed correctly.

[0030] In some embodiments, the nozzle includes a first housing and a second housing fitted inside the first housing; an air outlet path communicating with the air duct is formed between the first housing and the second housing; wherein, the interior of the second housing is provided with a cavity so that the second detection element can sense the distance between the measured object and the air outlet.

[0031] In some embodiments, the inner wall of the first housing near the air outlet is provided with a mounting member for installing the first magnetic structure, and the blower host is provided with a second magnetic structure near the outer wall to magnetically connect the nozzle.

[0032] The above solution employs a double-layer design of a first shell and a second shell to form a dedicated cavity, ensuring that the second detection element can accurately sense the distance and improving the ranging accuracy. At the same time, this structure optimizes the airflow path and improves the blowing effect.

[0033] In some embodiments, the blower host includes an annular air outlet disposed on the air outlet end, the annular air outlet and the air outlet path being interconnected; the first housing is connected to the outer side of the annular air outlet, and the second housing is connected to the inner side of the annular air outlet; wherein, the second detection element is disposed on the blower host located inside the annular air outlet, and the installation position of the second detection element is opposite to the outlet of the cavity of the second housing.

[0034] In some embodiments, the blower host is provided with an installation wall inside the annular air outlet, a light-transmitting plate is installed in the middle of the installation wall, and the second detection element is installed at one end of the light-transmitting plate inside the blower host.

[0035] Specifically, the light-beaming micro-hole device is provided between the light-transmitting plate and the second detection element, so that the effective detection angle of the second detection element is smaller and is not affected by the air nozzle.

[0036] The above solution uses a ring-shaped air outlet design for the blower unit, which works in conjunction with the double-layer structure of the nozzle to ensure that the detection unit is installed in a reasonable position and that the airflow is evenly distributed. This improves the accuracy of distance measurement and enhances the blowing effect, making the hot air distribution more uniform.

[0037] In some embodiments, the nozzle includes a first housing, within which an air outlet cavity is disposed, communicating with the air duct and the outside. The air outlet cavity enables the second detection element to sense the distance between the measured object and the air outlet end.

[0038] In some embodiments, the blower unit includes a housing, in which the air duct is formed, and the housing has a single-wall structure.

[0039] By adopting the above solution, the blower unit adopts a single-wall structure design, which simplifies the manufacturing process, reduces production costs, and at the same time reduces the weight of the equipment, improving portability and user comfort.
