Description

Technical Field

[0001] This utility model relates to the field of blower technology, and in particular to a blower that uses negative pressure air suction to mix tiny water droplets. Background Technology

[0002] Hair dryers are primarily used for drying and styling hair. As people's living standards continue to improve, they are paying more attention to hair care and maintenance. High-speed hair dryers can dry hair in a short time; however, the high air temperature of high-speed hair dryers quickly absorbs the moisture from the surface of the hair, making it even drier and rougher. Based on this, hair dryers with water ion modules have been designed.

[0003] In related technologies, such as the hair dryer disclosed in Chinese invention CN101444359A, a secondary airflow path is formed inside the expansion section, parallel to the main airflow path inside the casing. One end (rear end) of the secondary airflow path is a secondary intake port, and its other end (front end) is a secondary exhaust port. The secondary airflow path houses: a secondary electric blower, which is an integrated unit consisting of a secondary blower that draws in outside air through the secondary intake port and a secondary motor that drives the secondary blower; and an electrostatic device, serving as an ion generating device, located downstream of the secondary electric blower, which generates ionized micro-droplets of water. However, the inventors discovered during actual research and development that this type of hair dryer requires a secondary blower motor to provide airflow to the electrostatic device of the ion generating device, enabling the generated ionized micro-droplets to be blown out. This results in the hair dryer requiring two blowers, leading not only to a complex overall structure but also to high production costs.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a blower device that uses negative pressure air suction to mix tiny water droplets, effectively solving the technical defects of existing blowers, such as complex structure and high production cost.

By using the airflow blown out from the outer hot and cold air annular outlet, the inner water droplet annular outlet is in a negative pressure state, thereby sucking out the tiny water droplets in the water droplet channel and mixing them with the hot and cold airflow and blowing them onto the object being blown (such as hair); Meanwhile, the airflow from the outer hot and cold air annular outlet creates a negative pressure state at the inner water droplet annular outlet, thereby drawing out the tiny water droplets in the water droplet channel and mixing them with the hot and cold airflow before blowing them onto the object being blown. A single blower can be used to blow out the airflow and mix the tiny water droplets in the water droplet channel, eliminating the need for an additional blower inside the water droplet channel.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 6 The present application will now describe the blower device 10 that uses negative pressure air suction to mix tiny water droplets. The blower device 10 that uses negative pressure air suction to mix tiny water droplets includes a mica cylinder 11 and a heat insulation cylinder 12.

[0026] The mica cylinder 11 has a through cavity that extends axially through the front and rear surfaces of the mica cylinder 11, making the mica cylinder 11 a hollow annular structure. The heat insulation cylinder 12 is located inside the through cavity of the mica cylinder 11 and is coaxially arranged with the mica cylinder 11. The heat insulation cylinder 12 is smaller than the through cavity and encloses the hot and cold air channel 101. The heat insulation cylinder 12 has a water particle channel 102 with its opening facing forward. The heat insulation cylinder 12 extends forward and is flush with the front surface of the mica cylinder 11, forming a hot and cold air annular outlet 103 that connects to the hot and cold air channel 101 and a water particle annular outlet 104 that connects to the water particle channel 102. The water particle annular outlet 104 is located inside the hot and cold air annular outlet 103. The rear surface of the heat insulation cylinder 12 has an installation port 121. A water particle generator 20 is installed inside the heat insulation cylinder 12. The radiator 21 of the water particle generator 20 is located at the installation port 121 and closes the installation port 121.

[0027] Specifically, by installing a heat insulation cylinder 12 inside the cavity, a hot and cold air channel and a water droplet channel 102 are constructed. Simultaneously, the mica cylinder 11 and the heat insulation cylinder 12 construct a hot and cold air annular outlet 103 that connects to the hot and cold air channel 101 and a water droplet annular outlet 104 that connects to the water droplet channel 102. The water droplet annular outlet 104 is located inside the hot and cold air annular outlet 103. The airflow from the outer hot and cold air annular outlet 103 creates a negative pressure state at the inner water droplet annular outlet 104, thereby drawing out the tiny water droplets within the water droplet channel 102 and mixing them with the cold air. The hot air is blown onto the object being blown (e.g., hair) along with the hot air stream. At the same time, the air stream from the outer hot and cold air annular outlet 103 creates a negative pressure state at the inner water droplet annular outlet 104, thereby drawing out the tiny water droplets in the water droplet channel 102 and mixing them with the hot and cold air stream, which are then blown onto the object being blown. A single blower can be used to blow out the air stream and mix the tiny water droplets in the water droplet channel 102, eliminating the need for an additional blower in the water droplet channel 102. This simplifies the overall structure of the blower, allowing for a smaller size and reduced manufacturing costs.

[0028] It is understood that the blower device 10 with negative pressure suction and mixing of tiny water droplets provided by this utility model includes, but is not limited to, installation in hair dryers, hair combs, curling irons, heating clips and dryers.

[0029] In some embodiments, the water particle generator 20 further includes a cooler 22 stacked on the front surface of the radiator 21, a condenser rod 23 stacked on the front surface of the cooler 22, a first electrode 24 connected to the condenser rod 23, and a second electrode 25 located in front of the condenser rod 23. The cooler 22, the condenser rod 23, the first electrode 24, and the second electrode 25 are all located within the water particle channel 102. The rear surface of the radiator 21 is provided with heat dissipation fins 211, which extend rearward into the cavity. The radiator 21 itself closes the mounting opening 121, and the heat dissipation fins 211 are exposed within the hot and cold air channel 101. The airflow from the hot and cold air channel 101 blows onto the heat dissipation fins 211, thereby providing heat dissipation airflow to the radiator 21. This structure ensures that the water particle generator 20 is used more reliably.

[0030] It should be noted that the water droplet generator 20 can also be a water ion generator or other devices capable of producing tiny water droplets. By generating tiny water droplets through the device, the airflow blown out through the hot and cold air annular outlet 103 creates a negative pressure at the front end of the water droplet annular outlet 104. The negative pressure draws out the tiny water droplets in the water droplet channel 102 and mixes them with the airflow from the hot and cold air annular outlet 103, and finally blows them onto the object being blown. This structure not only simplifies the overall structure of the blowing device but also promotes miniaturization. At the same time, by setting the water droplet annular outlet 104 inside the hot and cold air annular outlet 103, it is ensured that the tiny water droplets output from the water droplet annular outlet 104 can be mixed with the airflow instead of being blown away, thereby improving the reliability and adhesion effect of the tiny water droplets to the object being blown.

[0031] Specifically, a component mounting shell 13 is installed inside the water particle channel 102, and the front surface of the component mounting shell 13 is flush with the front surface of the heat insulation cylinder 12; the mica cylinder 11 and the heat insulation cylinder 12 enclose a hot and cold air annular outlet 103, which is connected to the hot and cold air channel 101; the heat insulation cylinder 12 and the component mounting shell 13 enclose a water particle annular outlet 104. The cross-sectional area of ​​the hot and cold air annular outlet 103 is defined as a first width w1, and the cross-sectional area of ​​the water particle annular outlet 104 is defined as a second width w2, the value of which is half the value of the first width w1.

[0032] For example, the first width w1 of the hot and cold air annular outlet 103 is between 4.8mm and 5.2mm, and the second width w2 of the water droplet annular outlet 104 is between 2.3mm and 1.7mm. Preferably, the first width w1 is 5.0mm and the second width w2 is 2.5mm. Setting the second width w2 to half the value of the first width w1 ensures that the airflow of the hot and cold air annular outlet is sufficient while ensuring that the negative pressure generated at the front end of the water droplet annular outlet 104 is sufficient to draw out and mix the tiny water droplets in the water droplet channel 102. Preferably, both the hot and cold air annular outlet 103 and the water droplet annular outlet 104 are equipped with air outlet mesh 105.

[0033] More specifically, the component mounting housing 13 has a forward-opening component mounting cavity 131, within which a sensing element 132 is disposed. The sensing element 132 can be any of an infrared sensor, a distance sensor, a temperature control sensor, or a photoelectric sensor. The sensing element 132 is mounted within the component mounting cavity 131 via a component mounting bracket 133. The front side of the component mounting bracket 133 is provided with a protective cover 134 and a decorative shell 135 for covering the sensing element 132. By setting different types of sensing elements 132, the blower can achieve distance measurement, temperature control, or infrared irradiation functions.

[0034] In other embodiments, the hot and cold air channel 101 is provided with a heating element 14, which includes a plurality of mica sheets 141 arranged in a ring array and heating wires 142 wound around the plurality of mica sheets 141. It also includes a fan assembly 30, which includes a motor housing, a drive motor 31 mounted in the motor housing, and fan blades 32 mounted on the shaft of the drive motor 31. The motor housing includes an upper housing 33 and a lower housing 34 assembled together, which can enclose an airflow channel 35; the airflow channel 35 penetrates the rear surface of the motor housing to form an airflow inlet 36 and penetrates the front surface of the motor housing to form an airflow outlet 37; the mica tube 11 is interference-fitted to the airflow outlet 37.

[0035] Specifically, it also includes a control circuit board 40, which is installed inside the motor housing and located in front of the fan blade assembly 30; the centers of the control circuit board 40, mica tube 11, heat insulation tube 12, water particle generator 20, component mounting shell 13 and sensing element 132 are located on the same axis.

[0036] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
