Description

Technical Field

[0001] The utility model relates to a faucet-shaped fan. Background Art

[0002] At present, fans for drying hands have been widely used in household bathrooms or public toilets. Existing fans are generally installed independently in areas outside the wash basin, such as on the wall; however, in places with less space (such as household bathrooms), installing the entire fan on the wall will take up too much space, which is unacceptable. For this reason, there is also a concept that the fan is set like a faucet, and the larger exhaust fan and heater can be installed at the bottom of the basin. Above the basin, only the structure for air outlet is installed, which effectively utilizes the space of the basin; however, the air outlet structure above the basin needs to be redesigned.

[0025] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] In the description of the present invention, terms such as "up", "down", "left", "right", "front", "back", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0027] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 7As shown, the embodiment provides a faucet-shaped fan, including a faucet housing 10, a threaded mounting tube 50, an air guide inner tube 20, a nozzle 30 and a sensor 40; the structure of the faucet housing 10 in the embodiment has a curved segment design. Of course, in other embodiments, the shape of the faucet housing 10 can refer to the structure of other faucets on the market, but is not limited thereto. The threaded mounting tube 50 includes a threaded outer tube 51 and a ventilation inner tube 52 fixedly sleeved in the threaded outer tube 51. A wiring channel 501 is formed between the threaded outer tube 51 and the ventilation inner tube 52. The threaded outer tube 51 is a tube with external threads, and is equipped with a fixing nut 70 for installation on a basin. The threaded outer tube 51 is fixedly connected to the bottom of the faucet housing 10, and the upper end of the ventilation inner tube 52 and the upper end opening 502 of the wiring channel 501 are located in the faucet housing 10; the nozzle 30 is assembled at the outlet 11 of the faucet housing 10; the air guide inner tube 20 is arranged in the faucet housing 10, and the two ends of the air guide inner tube 20 are respectively connected to the ventilation inner tube 52 and the nozzle 30; thus, the ventilation channel is composed of the ventilation inner tube 52, the air guide inner tube 20 and the nozzle 30 connected in sequence. The sensor 40 is arranged at the outlet 11 of the faucet housing 10, and the connecting wire 41 of the sensor 40 passes through the gap between the faucet housing 10 and the air guide inner tube 20 and passes through the wiring channel 501 of the threaded mounting tube 50; the ventilation pipeline and the electrical circuit will not affect each other, and the connecting wire 41 of the sensor 40 will not affect the subsequent installation with the basin.

[0029] Specifically, in actual use, the threaded mounting tube 50 of the faucet-shaped fan is inserted into the mounting port of the basin from above the basin, and is locked from the bottom of the basin by the fixing nut 70. In this way, the lower port of the threaded mounting tube 50 is located at the bottom of the basin for connecting the air supply device, and the lower end opening 503 of the wiring channel 501 of the threaded mounting tube 50 is also located at the bottom of the basin. The connecting wire 41 of the sensor 40 extending from the wiring channel 501 directly enters the bottom of the basin to connect the control box.

[0030] Specifically, the sensor 40 is used to start the output airflow induction, that is, after installation, when the sensor 40 senses the hand (such as when the hand is placed in the corresponding outlet 11 position of the faucet housing 10, it is sensed by the sensor 40), the output is sent to the control box, and the control box controls the air supply device to work and realize the output of airflow. Its specific structure, model and connection method with the control box are all existing technologies, and can refer to the water outlet induction of existing water outlet faucets; it will not be described in detail here.

[0031] Specifically, in this embodiment, a mounting cavity is formed between the mouthpiece 30 and the faucet housing 10, and the sensor 40 is installed in the mounting cavity to provide a space for installing the sensor 40. More specifically, the mounting cavity is obtained by the outer wall of the mouthpiece 30 being recessed inward. Figure 6As shown, the outer wall of the nozzle 30 is recessed inward to form a mounting recess 31, and the sensor 40 is mounted at the mounting recess 31. This arrangement not only reserves space for mounting the sensor 40, but also shrinks the air outlet, allowing the output airflow to be faster and improve the drying effect.

[0032] The outer periphery of the mouthpiece 30 is provided with a sealing ring (defined as a first sealing ring 61), and the first sealing ring 61 cooperates with the inner wall of the faucet housing 10; such a configuration can effectively isolate the water vapor from the external environment and prevent the water vapor from entering the faucet housing 10 from the outlet 11 of the faucet housing 10. At the same time, the outer periphery of the mouthpiece 30 is also provided with a clearance notch 32 for the connection line 41 of the sensor 40 to pass through, and the connection line 41 is passed through the clearance notch 32, effectively constraining the connection line 41.

[0033] The outer periphery of the ventilation inner tube 52 is provided with a long strip-shaped recess 521, and the recess 521 extends along the axial direction of the ventilation inner tube 52. The channel formed by the recess 521 and the threaded outer tube 51 is the wiring channel 501. The molding is simple. When assembling, the connecting wire 41 can be firstly arranged in the recess 521 of the ventilation inner tube 52, and then the ventilation inner tube 52 and the threaded outer tube 51 are assembled.

[0034] The bottom of the faucet housing 10 also has an extension portion 12 extending radially inward, and the threaded outer tube 51 is fixedly connected to the inner side wall of the extension portion 12. Specifically, the threaded outer tube 51 is connected to the inner side wall of the extension portion 12 by threads. The bottom surface of the extension portion 12 is provided with an annular groove 13, and a sealing ring (defined as a second sealing ring 62) is installed in the annular groove 13. When installed on the basin, the extension portion 12 at the bottom of the faucet housing 10 abuts against the basin, and the second sealing ring 62 in the annular groove 13 is sealed and abutted against the surface of the basin. In this way, it can effectively prevent water on the basin from leaking downward from the installation port of the basin to protect the components at the bottom of the basin.

[0035] The air guide inner pipe 20 is a corrugated pipe, which has good flexibility and is not easy to fold, and can be adapted to faucet housings 10 of different shapes. Of course, in other embodiments, other flexible or rigid pipes can also be used.

[0036] Furthermore, in this embodiment, the nozzle 30 is also equipped with a temperature sensor 80. The connection line (not shown) of the temperature sensor 80, like the connection line 41 of the sensor 40, also passes through the gap between the faucet housing 10 and the air guide inner tube 20 and passes through the wiring channel 501 of the threaded mounting tube 50. The temperature sensor 80 is used to sense the temperature of the airflow blown out from the nozzle 30. The temperature sensor 80 is connected to the control box and transmits the sensed temperature to the control box. The control box controls the heater for heating the airflow according to the actual blown temperature, thereby playing a role in temperature adjustment. Specifically, the connection relationship between the temperature sensor 80, the control box and the heater and the control principle are all existing technologies, which have been mastered and implemented for a long time and will not be described in detail here.

[0037] Specifically, the nozzle 30 is provided with a mounting hole 33, and the temperature sensor 80 is assembled in the mounting hole 33 of the nozzle 30 and forms a sealing fit with the nozzle 30 through a sealing ring (defined as a third sealing ring) to prevent air leakage.

[0038] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
