Description

Technical Field

[0001] This utility model relates to the field of cotton swab drying technology, specifically to an energy-saving cotton swab drying oven. Background Technology

[0002] Cotton swabs are a common household item, typically consisting of a thin wooden or plastic stick with cotton wrapped around both ends. They are widely used in personal care, medical cleaning, cosmetics, and household cleaning. During the manufacturing process, cotton is glued to the swab and then heated to allow the adhesive to fully adhere to the cotton.

[0003] A common device for drying cotton swabs includes a mounting frame, a toothed chain mounted on the mounting frame, and a hot air blower. The cotton swabs are placed on the toothed chain for conveying, and the hot air blower is fixed on the mounting frame with its air outlet facing downwards. The cotton swabs are located below the air outlet of the hot air blower. When drying, the hot air blower is turned on, allowing the toothed chain to move the cotton swabs past the area below the air outlet. The hot air blown from the air outlet comes into contact with the cotton swabs. To ensure thorough drying of the cotton swabs, multiple hot air blowers are installed on the mounting frame to achieve the desired drying effect.

[0004] The above-mentioned technical conditions also have the drawback that the hot air blown out by the hot air blower is leaked into the air after passing through the cotton swabs, resulting in excessive waste of heat energy and poor drying efficiency.

[0005] Based on this, this utility model designs an energy-saving drying oven for cotton swabs to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving drying oven for cotton swabs, comprising a fixed frame, a placement cover, a fixed cover, and a toothed chain disposed on the fixed frame. Cotton swabs are placed on the toothed chain. The placement cover covers the toothed chain, and the fixed cover covers the placement cover. A heating rod is fixedly disposed on the fixed cover, and the heating rod is located between the fixed cover and the placement cover. An air extraction port is provided on the placement cover, and an exhaust fan is disposed in the air extraction port. The exhaust fan draws air upward. A ventilation hole is provided on the side wall of the placement cover, and a clearance hole is provided on the upper side wall of the placement cover.

[0007] By adopting the above technical solution, during the drying process, the heating rod heats the air, while the exhaust fan is driven to draw in air, causing the airflow to flow. The airflow enters the placement hood through the ventilation hole and then enters the fixed hood through the clearance hole on the upper side. The airflow continuously circulates in a relatively sealed environment, reducing gas outflow, improving heating efficiency, and achieving the effect of reducing heat loss.

[0008] Preferably, a baffle is fixedly provided in the placement cover, and a drainage hole is provided on the baffle, which is located above the cotton swab.

[0009] By adopting the above technical solution, the drainage hole guides the hot air, and when the air is drawn out, the hot air is guided through the cotton swab, which further improves the drying effect of the cotton swab.

[0010] Preferably, a water-absorbing layer is provided on the upper part of the vent hole.

[0011] By adopting the above technical solution, when the airflow passes through the vent, the water-absorbing layer absorbs the moisture carried by the airflow, thereby reducing the moisture carried by the airflow.

[0012] Preferably, a heat insulation cover is fixedly installed on the fixing frame, and the heat insulation cover covers the fixing cover.

[0013] By adopting the above technical solution, the heat insulation cover further isolates the fixed cover from the outside world, further reducing the heat loss in the fixed cover.

[0014] Preferably, a heat insulation layer is fixedly provided between the fixed cover and the heat insulation cover.

[0015] By adopting the above technical solution, the heat insulation layer further isolates the fixed cover from the outside world, while reducing heat loss and further improving drying efficiency.

[0016] Preferably, a pressure plate is fixedly provided on the baffle, and the pressure plate is located above the cotton swab.

[0017] By adopting the above technical solution, when the airflow is used for drying, the pressure plate is located above the cotton swabs to block them, which can prevent some cotton swabs from falling off the toothed chain due to excessive airflow.

[0018] In summary, this application has the following beneficial technical effects: During drying, the heating rod heats the air, and at this time, the exhaust fan is driven to extract the air, which causes the airflow to flow. The airflow enters the placement hood through the vent and enters the fixed hood through the clearance hole on the upper side. The airflow continuously circulates in a relatively closed environment, reducing gas outflow, improving heating efficiency, and achieving the effect of reducing heat loss.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] Reference Figures 1-4 An energy-saving drying oven for cotton swabs includes a fixed frame 1, a placement cover 2, a fixed cover 3, and a toothed chain 4 mounted on the fixed frame 1. Cotton swabs are placed on the toothed chain 4. The placement cover 2 covers the toothed chain 4, and the fixed cover 3 covers the placement cover 2. A heat insulation cover 5 is fixedly mounted on the fixed frame 1, covering the fixed cover 3. A mounting plate 6 is fixedly mounted on the fixed cover 3, and a heating rod 7 is fixedly mounted on the mounting plate 6. In this embodiment, the heating rod 7 is an electric heating rod 7. The heating rod 7 is located between the fixed cover 3 and the placement cover 2, and multiple heating rods 7 are arranged in the fixed cover 3.

[0029] Reference Figures 1-4 The placement cover 2 has an air extraction port 8, and an exhaust fan is installed in the air extraction port 8. The exhaust fan includes a mounting cylinder 9 and fan blades 10. The mounting cylinder 9 is fixedly installed in the air extraction port 8, and the fan blades 10 are located in the mounting cylinder 9. A motor 11 is fixedly installed on the placement cover 2. A rotating rod 12 is coaxially fixedly connected to the rotating shaft of the motor 11. The rotating rod 12 passes through the fixed cover 3 and is located in the mounting cylinder 9. The fan blades 10 are fixedly connected to the rotating rod 12, and multiple fan blades 10 are installed on the rotating rod 12. The drive motor 11 drives the rotating rod 12 to rotate, so that the fan blades 10 rotate quickly and drive the airflow upward. At this time, the mounting cylinder 9 can concentrate the airflow and extract it upward, reducing the dispersion of airflow.

[0030] Reference Figures 1-4 The exhaust fan draws air upwards. Ventilation holes 13 are located on the side wall of the placement cover 2, arranged in two rows at both ends of the cotton swabs. A clearance hole 14 is located on the upper side wall of the placement cover 2. During drying, the heating rod 7 is turned on for heating. At this time, the drive motor 11 drives the fan blades 10 to rotate and draw air, causing the airflow to circulate. The airflow enters the placement cover 2 through the ventilation holes 13, and then enters the fixed cover 3 through the clearance hole 14 and the mounting cylinder 9. The heated airflow is sent into the placement cover 2 to contact the cotton swabs, and then enters the fixed cover 3, continuously circulating in a relatively sealed environment to dry the cotton swabs, reducing gas outflow, improving heating efficiency, and achieving the effect of reducing heat loss.

[0031] Reference Figures 1-4 A baffle is fixedly installed in the placement cover 2, and a drainage hole 15 is opened on the baffle. The drainage hole 15 is located above the cotton swab. In this embodiment, the drainage hole 15 is located in the middle of the baffle. When drying, the airflow enters the placement cover 2 through the two ventilation holes 13 and flows towards the middle under the guidance of the drainage hole 15, so that the airflow can come into more full contact with the cotton on the cotton swab and improve the drying effect of the cotton swab.

[0032] Reference Figures 1-4 A water-absorbing layer (not shown in the figure) is provided in the upper part of the vent 13. In this embodiment, the water-absorbing layer is made of porous absorbent cotton. When the airflow passes through the vent 13, the water-absorbing layer absorbs the moisture carried by the airflow, reducing the moisture carried by the airflow. The heat insulation cover 5 further isolates the fixed cover 3 from the outside world. A heat insulation layer (not shown in the figure) is fixedly provided between the fixed cover 3 and the heat insulation cover 5. In this embodiment, the heat insulation layer is an asbestos heat insulation layer. The heat insulation layer further isolates the fixed cover 3 from the outside world, while reducing heat loss and further improving drying efficiency.

[0033] Reference Figures 1-4 A pressure plate 16 is fixedly installed on the baffle. The pressure plate 16 is located above the cotton swab. The pressure plate 16 does not contact the cotton swab. When the airflow is used for drying, the pressure plate 16 is located above the cotton swab and blocks the cotton swab, which can prevent some cotton swabs from falling off the toothed chain 4 due to excessive airflow.

[0034] The implementation principle of this embodiment is as follows: the heated airflow is sent into the placement cover 2 to contact the cotton swabs, and then enters the fixing cover 3. It continuously circulates in a relatively closed environment to dry the cotton swabs, reduce gas outflow, improve heating efficiency, and achieve the effect of reducing heat loss and improving drying efficiency.
