Technical Field

[0001] The utility model relates to the field of blowing devices, in particular to a blowing device with a honeycomb heating tube. Background Art

[0002] In daily life, in order to quickly dry and style the washed hair, a hair dryer is a commonly used household appliance, which drives an air flow through a motor to dry and shape the hair. In a traditional hair dryer, a heating element is directly arranged in a shell, and hot air can be obtained when the blower blows towards the heating element. However, there is a large amount of heat loss in the use of hot air in this way, and the wind speed is relatively small; although there are also some honeycomb structures arranged at the air outlet, the honeycomb structures are often used for noise reduction and do not improve the air volume, wind speed and air temperature of the blowing device.

[0003] Chinese Patent Publication No. CN221044457U relates to an energy-saving and power-saving hair dryer, belonging to the technical field of daily necessities. It includes a shell, an air inlet and an air outlet are oppositely arranged at two ends of the shell, a wind guide sleeve is arranged inside the shell, a brushless motor, a ceramic heating element and a mica frame are arranged inside the wind guide sleeve, a fan is arranged inside the brushless motor, the ceramic heating element is fixedly connected with the mica frame, the ceramic heating element is fixed inside the wind guide sleeve through the mica frame, and a plurality of honeycomb holes are arranged on the ceramic heating element, so that the ceramic heating element is in a honeycomb shape; outside the mica frame, there are several circles of surrounding heating wires; in this solution, since the ceramic heating element is in a honeycomb shape, air will gather and stay at the ceramic heating element, increasing the contact time with the ceramic heating element, and effectively heating the air. Under the condition that the blown hot air reaches the same temperature, the honeycomb-shaped ceramic heating element can save 20-30% of electric energy. In this patent, only honeycomb ceramics are used as the heating element, and the hot air after coming out of the heating element has a certain temperature drop, resulting in heat loss.

[0004] Chinese Patent Publication No. CN220212216U relates to an air inlet duct module of a noise-reducing hair dryer. It includes an inner duct shell, a PCB board, a noise-reducing honeycomb net, a high-speed motor and a heater. Along the flow direction of the air duct, the PCB board, the noise-reducing honeycomb net, the high-speed motor and the heater are sequentially installed inside the inner duct shell, and an air outlet and an air inlet are respectively arranged at the front end and the rear end of the inner duct shell. By adding a noise-reducing honeycomb net between the air inlet duct provided with the PCB board and the air inlet of the motor, the air flow in the air inlet duct is converged and rectified by the noise-reducing honeycomb net, so that the air flow entering the motor is more stable, reducing the influence of the air flow disturbance at the PCB board on the air inlet of the motor and reducing the wind noise. In this patent, a honeycomb net is arranged at the air outlet, which only plays a role in noise reduction and does not improve the wind speed and air temperature. Summary of the Utility Model

It is characterized in that: a heating assembly is further arranged in the fluid channel, the heating assembly is connected to the control board, and the blower and the heating assembly are controlled to work through the control board. The heating assembly includes a honeycomb-shaped air duct. The blower enables the fluid to enter the fluid channel through the air inlet, and after the fluid temperature is changed under the action of the heating assembly, it is discharged from the air outlet through the honeycomb-shaped air duct for operation.

[0008] Preferably, the honeycomb-shaped air duct is formed by multiple groups of air ducts, and a heat insulation bracket is sleeved outside the honeycomb-shaped air duct.

[0009] Preferably, a heat insulation baffle is arranged between the end of the honeycomb-shaped air duct and the air outlet.

[0032] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0033] A blowing device with a honeycomb-shaped heating tube according to the preferred embodiment of the present utility model; As Figure 1-2As shown in the figure, it includes a housing 10. The housing is divided into upper and lower parts. The lower part forms a handle 103, and the upper part forms a fluid channel 102. There are openings on both the left and right sides of the fluid channel, and a fluid channel isolation cover 20 is connected at the openings. A control board 40, a control button 50 connected to the control board, and a battery 30 are arranged inside the handle. A blower 60 and a heating component 80 are arranged inside the fluid channel. Both the blower and the heating component are connected to the control board. The control board controls the rotation of the blower to make the fluid flow inside the fluid channel, and the control board controls the heating component to heat. After the fluid passes through the heating component, it is changed to heat the fluid and is blown out under the action of the blower. By holding the handle, the direction of the heated fluid is adjusted to realize the use of the blowing device.

[0034] Specifically, as Figure 2-3 shown in the figure, an air inlet 105 is formed on the left side of the fluid channel 102, and an air outlet 106 is formed on the right side. An air inlet cover 200 is sleeved on the air inlet, and an air outlet cover 201 is sleeved on the air outlet. The blower 60 is arranged close to the air inlet, and the heating component 80 is arranged close to the air outlet. The blower 60 works to suck the fluid into the fluid channel through the air inlet, and blows the fluid towards the heating component under the action of the blower to heat the fluid, and discharges the heated fluid through the air outlet. In order to make more of the fluid sucked by the blower pass through the heating component and be discharged, silica gel sleeves 70 are sleeved outside both the blower and the heating component, and the two groups of silica gel sleeves are connected to each other to prevent the loss of fluid during the process of the blower blowing the fluid towards the heating component.

[0035] Furthermore, as Figure 1-3 and Figure 7-10 shown in the figure, the housing 10 includes a left housing 100 and a right housing 101, and connection rings 107 are arranged on both the left and right sides of the upper part of the housing. Among them, a bayonet 1070 is arranged on the connection ring on the side of the air inlet, and a rotating clamping groove is arranged on the connection ring on the side of the air outlet. The rotating clamping groove includes an insertion groove 1071 arranged on the connection ring and a rotating groove 1072 connected to the insertion groove. Clamping arms 1073 are arranged on both sides of the insertion groove, and a limiting post 1074 is arranged inside the rotating groove. The air outlet cover 201 is connected to the housing at the connection ring. An isolation net is arranged on the air outlet cover, and a clamping block 203 is arranged on the inner wall of the end connected to the housing. There is a gap 204 between the clamping block and the isolation net 202. Insert the clamping block into the rotating groove through the insertion groove, and rotate the air outlet cover to make the clamping block enter the rotating groove, and the clamping arms are placed in the gap. At this time, the clamping arms generate a clamping force on the clamping block to realize the connection between the air outlet cover and the housing. When disassembling, rotate in the opposite direction. When the clamping block rotates to the position where it contacts the limiting post, the connection between the air outlet cover and the housing is completed. The air inlet cover has the same structure as the air outlet cover. After aligning the clamping block with the bayonet 1070 and pressing, the clamping block is snapped into the bayonet to complete the detachable connection between the air inlet cover and the housing. Both of these two detachable connection methods are applicable to the connection between the air inlet cover and the air outlet cover and the housing.

[0036] Further, as shown in Figure 2-6 and Figure 11-12 , multiple groups of circumferentially arranged reinforcing ribs 108 are provided inside the housing. A clamping groove 1080 is formed in the middle of the reinforcing rib close to the blower. An external convex column 700 is provided on the silicone sleeve 70 connected to the blower corresponding to the clamping groove, preventing the blower from rotating inside the housing. At the same time, an internal convex ring 701 is provided at one end of the silicone sleeve, and the internal convex ring is close to the air inlet direction, so that the blower can only be connected to the silicone sleeve from the other side. At the same time, a retaining ring 104 is also provided at the air inlet, and the retaining ring limits the blower. By sleeving the silicone sleeve outside the blower, the vibration during the operation of the blower is reduced from being transmitted to the housing, and at the same time, the noise can also be reduced. The provided reinforcing ribs can increase the strength of the housing, and at the same time, the reinforcing ribs reduce the contact area between the silicone sleeve and the housing, further reducing the transmission of the blower vibration. The heating component 80 is formed by a heating tube group 800. The heating tube group is formed by splicing multiple groups of heating tube units 805. In the present utility model, it is spliced into a honeycomb shape, and it can also be spliced into other shapes, that is, it can heat itself while guiding the air. All these should fall within the protection scope of the present utility model. At the same time, the formation of the air guide tube is not limited to a straight line shape, and it can also be bent or other special-shaped shapes, which will not be specifically described here. An external mica sheet 801 is provided outside the heating tube group, and the silicone sleeve is sleeved outside the external mica sheet. An internal mica sheet 803 can be provided in the middle of the heating tube group. At the same time, clamping grooves 804 can be provided on both the external mica sheet and the internal mica sheet, and mica retaining sheets 802 are provided in the clamping grooves. The mica retaining sheets are placed at the air outlet of the heating tube group, leaving a gap between the heating tube group and the air outlet.

[0037] The heating tube group is connected to the control board and uses its own heat generated after being powered on to heat the fluid blown by the blower when the fluid contacts the heating tube, realizing a larger contact area between the fluid and the heating tube and better heating efficiency. A heating body can also be provided between the blower and the heating tube group, and the blower blows the fluid towards the heating body to heat the fluid, and then the fluid passes through the heating tube group and is blown out through the air outlet, thereby improving the wind speed and air volume. However, the heat transfer of this method is slightly lower than that of the heating tube group generating heat by itself. At the same time, the mica retaining sheet provided between the heating tube group and the air outlet also avoids the too high temperature at the air outlet, making the use safer and more efficient. And through experimental comparison, it can be known that the blowing device of the present utility model has various advantages compared with the Laifen hair dryer during use. Its tests on air volume, noise, wind speed, and wind pressure have greater advantages compared with the Laifen hair dryer. The specific test conditions, test methods, and test results are shown in Table 1.

[0039]

[0040] Further, as shown in Figure 11-13As shown, the left housing 100 and the right housing are connected by a clamping structure, and a sealing structure is provided at the connection. The clamping structure includes a clamping block provided on the left housing and a convex block provided on the right housing. The convex block and the clamping block are connected to achieve clamping. The sealing structure includes a sealing groove 1001 provided on the left housing and a sealing post 1011 provided on the right housing. The sealing post is snapped into the sealing groove to achieve sealing.
