[0001] This utility model relates to the field of vehicle hair dryer technology, specifically a vehicle hair dryer with a self-rotating brush head. Background Technology

[0002] Car hair dryers are commonly used to blow away dust and particles inside a car, making them a good car cleaning tool. Most existing car hair dryers have brush heads attached to their nozzles to clean up dust or particles that are difficult to blow away; for example... Figure 1 As mentioned above, the applicant's existing products also have brush heads for cleaning; however, these existing brush heads require manual manipulation of the car hair dryer for cleaning, which is laborious and inconvenient. To solve the above problems, this utility model provides a car hair dryer with a self-rotating brush head. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a vehicle-mounted hair dryer with a self-rotating brush head. The self-rotating brush head is externally mounted on the end of the blower tube. When airflow is blown out of the blower tube, the airflow passes through spiral air holes and strikes a spiral air receiving plate, driving the self-rotating brush head to rotate. This achieves effective cleaning of the end of the blower tube while the rotating brush head effectively cleans; thus solving the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a car hair dryer with a self-rotating brush head, comprising: a blower pipe installed on the car hair dryer, a self-rotating brush head rotatably mounted on the outer end of the blower pipe, the self-rotating brush head comprising a self-rotating tube and bristles evenly distributed in a ring at the end of the self-rotating tube; a plurality of spiral air holes evenly distributed in a ring along the circumferential direction are formed on the inner side of the end of the blower pipe, and a plurality of spiral air receiving plates evenly distributed in a ring along the circumferential direction are formed on the inner side of the self-rotating tube, the spiral air receiving plates being positioned corresponding to the spiral air holes and having opposite spiral directions.

[0005] Preferably, the air inlet of the spiral air hole is integrally connected to the spiral air duct, and the spiral air duct has the same spiral angle as the spiral air hole.

[0006] Preferably, the air inlet and air outlet of the spiral air hole are located on the inner and outer sides of the air blowing pipe, respectively; along the direction of airflow in the air blowing pipe, the air inlet is located in front of the airflow, and the air outlet is located behind the airflow.

[0007] Preferably, the number of spiral air receiving plates is greater than the number of spiral air holes, the arc between the air outlets of two adjacent spiral air holes is D1, the arc of the spiral air receiving plate extending along the circumference of the self-rotating tube is D2, and D2 is greater than D1.

[0008] Preferably, the top end of the self-rotating tube is coaxially connected to an annular plate, the inner side of the annular plate is coaxially integrally connected to a rotating ring, an annular groove is opened on the outer side of the blower tube, and the rotating ring is rotatably installed in the annular groove.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model features a self-rotating brush head mounted externally at the end of a blower pipe. When the blower pipe blows out air, the airflow passes through the spiral air holes and strikes the spiral air receiving plate, driving the self-rotating brush head to rotate. This allows the rotating brush head to effectively clean the end of the blower pipe while the blower pipe is blowing air, making it convenient and practical.

[0011] 2. The air inlet of the spiral air hole of this utility model is integrally connected to the spiral air duct. The spiral air duct and the spiral air hole have the same spiral angle and direction, forming a smooth air duct. The spiral air duct facilitates the introduction of airflow from the blower pipe into the spiral air hole, improving the driving effect of the airflow on the self-rotating tube.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] like Figures 1 to 10 As shown, this embodiment provides a car hair dryer with a self-rotating brush head, including: a blower tube 2 installed on the car hair dryer 1, and a self-rotating brush head 3 rotatably installed on the outer end of the blower tube 2. The self-rotating brush head 3 includes a self-rotating tube 31 and bristles 32 evenly distributed in a ring at the end of the self-rotating tube 31. Specifically, a ring plate 34 is coaxially connected to the top of the self-rotating tube 31, and a rotating ring 35 is coaxially integrally connected to the inner side of the ring plate 34. An annular groove 23 is opened on the outer side of the blower tube 2, and the rotating ring 35 is rotatably installed in the annular groove 23. In fact, the cross-section of the annular groove 23 is a chamfered circle, which is a superior arc chamfered circle, ensuring that the rotating ring 35 will not fall out of the annular groove 23 while rotating in the annular groove 23, which is convenient and practical.

[0027] like Figures 3 to 6As shown, a number of spiral air holes 21 are evenly distributed in a ring along the circumference on the inner side of the end of the blower pipe 2. Specifically, the air inlet and air outlet of the spiral air holes 21 are located on the inner and outer sides of the blower pipe 2, respectively. Along the direction of airflow in the blower pipe 2, the air inlet is located in front of the airflow and the air outlet is located behind the airflow. The airflow in the blower pipe 2 is blown out from the spiral air holes 21, and the airflow acts on the self-rotating tube 31, driving the self-rotating tube 31 to rotate. More specifically, the air inlet of the spiral air hole 21 is integrally connected to the spiral air guide pipe 22. The spiral air guide pipe 22 and the spiral air hole 21 have the same spiral angle and direction, forming a smooth air guide channel. The spiral air guide pipe 22 facilitates the introduction of the airflow in the blower pipe 2 into the spiral air hole 21, improving the driving effect of the airflow on the self-rotating tube 31.

[0028] like Figures 7 to 10 As shown, several spiral air receiving plates 33 are evenly distributed in a ring along the circumferential direction on the inner side of the self-rotating tube 31. The spiral air receiving plates 33 correspond to the spiral air holes 21 in position but have opposite spiral directions. The corresponding position here refers to the height correspondence, that is, the airflow blown out of the spiral air holes 21 can be blown onto the spiral air receiving plates 33, thereby achieving good drive. In addition, the design of the spiral air receiving plates 33 and the spiral air holes 21 having opposite spiral directions makes the airflow blown out of the spiral air holes 21 almost perpendicular to the surface of the spiral air receiving plates 33, resulting in better drive effect. Specifically, the number of spiral air receiving plates 33 is greater than the number of spiral air holes 21, which facilitates the spiral air holes 21 blowing onto the spiral air receiving plates 33. The arc between the air outlets of two adjacent spiral air holes 21 is D1, and the arc of the spiral air receiving plate 33 extending along the circumference of the self-rotating tube 31 is D3, where D3 is greater than D1. By setting D3 to be greater than D1, it is ensured that the airflow blown from the air outlets of the spiral air holes 21 can hit the spiral air receiving plates 33, thus achieving good drive.

[0029] This invention features a self-rotating brush head 3 externally mounted on the end of a blower pipe 2. When the blower pipe 2 blows air, the airflow passes through the spiral air hole 21 and impacts the spiral air receiving plate 33, driving the self-rotating brush head 3 to rotate. This achieves effective cleaning of the end of the blower pipe 2 while the rotating brush bristles 32 perform cleaning simultaneously, making it convenient and practical. Simultaneously, the air inlet of the spiral air hole 21 is integrally connected to the spiral air guide pipe 22. The spiral air guide pipe 22 and the spiral air hole 21 have the same spiral angle and direction, forming a smooth airflow channel. The spiral air guide pipe 22 facilitates the introduction of airflow from the blower pipe 2 into the spiral air hole 21, improving the driving effect of the airflow on the self-rotating pipe 31. Furthermore, the spiral air receiving plate 33 corresponds to the spiral air hole 21 in position but has the opposite spiral direction, ensuring that the airflow from the spiral air hole 21 hits the surface of the spiral air receiving plate 33 almost vertically, resulting in even better driving effect.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
