Description

Technical Field

[0001] The utility model relates to a portable air blower and dryer, in particular to a portable air blower and dryer used in the field of air blower and drying of vehicle mats. Background Art

[0002] Before cleaning the vehicle mat, it is usually necessary to fix the mat in a certain position and then clean it. After cleaning, it is naturally air-dried. Cleaning is generally done by clamping the workpiece and then using a manual spray gun to spray foam water or clean water for cleaning.

[0003] After cleaning, the mat needs to be blown dry. Currently, there are automatic blow dryers. Put the cleaned mat into the blow dryer. The control module controls the motion mechanism to drive the blower to blow and dry the moisture on the surface of the mat. The blower is connected to the gas generator. The gas generator generates hot air to blow to the surface of the mat to accelerate the evaporation of moisture and quickly blow dry the mat. However, this automatic blow dryer is large in size and weight, not convenient to carry, not suitable for home or personal use, and has high cost. In addition, the electronic control is relatively complicated. It is necessary to detect the temperature and humidity of the mat surface in real time to determine whether the mat has been blown dry, and many electronic components are required.

[0004] There are more hair dryers on the market that are used to blow dry pet hair, but the air outlet of this type of hair dryer is not easy to replace, and the air volume and temperature do not meet the standards for blowing and drying vehicle mats. There is no detection and monitoring of the fan and heating module, and other abnormalities are prone to occur in the event of failure or damage.

[0005] As mentioned above, there are problems that need to be solved urgently, and it is urgent to develop a portable blow dryer for vehicle mats for home or personal use. Utility Model Content

[0006] The utility model is designed to solve the above problems and can at least solve one of the above problems. The technical problem to be solved by the present invention is to provide an economical portable hair dryer that can be easily placed, used for personal or household use, takes up little space, is not prone to failure and is highly efficient.

[0007] To achieve the above-mentioned purpose, the utility model is a portable hair dryer as follows, characterized in that it includes a main unit, a gas working module, a flexible tube, an air outlet, a control unit, a first current detection module and a second current detection module; the gas working module also includes a gas generator and a heating module, the gas generator is accommodated in the main unit, the gas working module, the flexible tube and the air outlet are connected in sequence, the gas working module generates hot air from the flexible tube and the air outlet for blowing and drying the mat; the first current detection module and the second current detection module are electrically connected to the control unit, the first current detection module is used to detect the current flowing through the gas generator, and the second current detection module is used to detect the current flowing through the heating module.

[0008] In the technical solution constructed as above, the gas working module, the flexible tube and the air outlet are connected in sequence, the gas working module also includes a gas generator and a heating module, the gas generator can generate fluid and then generate hot air through the heating module, or the gas generator can inhale air from the outside and generate hot air after passing through the gas generator, the hot air generated by the gas working module passes through the channel of the flexible tube and then blows out from the air outlet, the main unit is placed on the ground, the air outlet is held in the hand, and due to the telescopic ductility of the flexible tube, the cleaned mat can be blown and dried within a longer radius or by movement; the first current detection module and the second The current detection module is electrically connected to the control unit, the first current detection module is used to detect the current flowing through the gas generator, and the second current detection module is used to detect the current flowing through the heating module. The first current detection module and the second current detection module respectively feed back the current value passing through the gas generator and the current value of the heating module to the control unit, and the control unit controls the information in a predetermined form to prompt whether the current is too large or too small to evaluate whether the currently working gas generator and heating module are working normally or whether a fault occurs, so as to intuitively reflect whether the entire portable hair dryer is working normally.

[0009] In the present technical solution, preferably, the number of the gas generators is at least two, and the at least two gas generators are connected to the same air outlet via a multi-way pipe.

[0010] In the technical solution constructed as above, since the number of the gas generators is at least two, the at least two gas generators are connected to the same air outlet through a multi-way pipe; in this way, the wind generated by two, three or more gas generators converges into one air duct, and the air volume is doubled. When the portable hair dryer generates hot air to blow and dry the mat, the blowing and drying efficiency is greatly improved and the blowing and drying time is shortened.

[0011] In the present technical solution, the heating module is preferably installed on the air outlet channel of the multi-way pipe.

[0012] In the technical solution constructed as above, since the heating module is installed on the air outlet channel of the multi-way pipe, the fluid air generated by the gas generator is blown toward the pad through the flexible tube and the air outlet nozzle after passing through the heating module. Compared with the heating module being installed at the air inlet of the gas generator and passing through the air outlet of the gas generator, the hot air fluid has fewer paths to travel, heat is not easily lost, the air outlet temperature is high and it is not easy to block the air inlet of the gas generator.

[0013] In the present technical solution, the heating module is preferably a heating wire.

[0014] In the technical solution constructed as above, the fluid air generated by the gas generator encounters little obstruction when passing through the heating wire, the air outlet is smooth and the air outlet volume is basically unaffected, and the temperature of the heating wire rises quickly, so hot air can be generated quickly.

[0019] In the present technical solution, the quick-connect structure is preferably a snap-connect structure.

[0020] In the technical solution constructed as above, the nozzle is fluidly connected to the flexible tube through the snap-fit ​​structure. Compared with the traditional threaded connection method, it can be snap-fitted and rotated into place at one time, which saves time and effort. The traditional threaded connection requires the nozzle to be rotated dozens of times before it can be connected to the flexible tube, and its replacement is time-consuming and labor-intensive.

[0021] In the technical solution, preferably, a support frame is detachably connected to the bottom of the main machine.

[0022] In the technical solution constructed as above, when using a portable hair dryer, the main unit can be supported on the ground by a support frame to prevent direct contact with the ground and the influence of water vapor. When the support frame is detachably connected, the support frame under the main unit can be disassembled and stored when not in use.

[0023] In the present technical solution, the host can preferably be mounted on a wall.

[0025] In this technical solution, the host is hung on the wall through a dovetail groove structure.

[0026] In the technical solution constructed as above, compared with the simple and reliable form of plug-in or rope binding, the dovetail groove structure is a simple and practical structure and is easy to form. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0043] It is understandable that the mat of the embodiment of the utility model is not limited to the mat in the vehicle, nor is it limited to the short mat and the long mat in the vehicle, and is further not limited to the mat at the door of the house or the mat at the door of the bathroom.

[0044] It should be noted that, for the sake of ease of explanation, the following only takes the example of placing the mat in a vehicle in the portable blow dryer of the present application for blowing and drying the cleaned vehicle mat, but the present invention is not limited to this.

[0045] The gas working module should be interpreted in a broad sense. The gas working module can be a fan with an internal integrated heater, a fan without an internal heater and a working component connected to an external heating module (the heating module can be connected to the air outlet or air inlet of the fan), an air compressor with an external heating module, an air compressor with an internal integrated heater, and other parts, units, devices or systems that can generate hot air.

[0046] The term flexible pipe may refer to a hose, a flexible pipe, a plastic pipe having elasticity, an elastically deformable pipe, etc.

[0047] Figure 1-Figure 11 The first embodiment of the portable hair dryer 1000 of the present application is shown as an example. Figure 1-3The portable hair dryer 1000 includes a main unit 1, a muffler 2, a flexible tube 3, an air outlet 4, and a gas working module 13. The main unit 1, the muffler 2, the flexible tube 3, and the air outlet 4 are fluidically connected in sequence; the main unit 1 includes a lower shell 11, an upper shell 12, and a gas working module 13. The lower shell 11 is composed of a left wall, a right wall, a front wall, a rear wall, and a bottom wall, and is roughly a rectangular parallelepiped shape. The upper shell 12 is a prism-shaped shape, with a large lower part and a small upper part. The lower shell 11 and the upper shell 12 are spliced ​​together to form a storage space, and the gas working module 13 is stored in the storage space. The lower shell 11 and the upper shell 12 can also be other shapes, such as cylindrical, polyhedral, or three-dimensional shapes with curved surfaces. The present application is not limited by the shape.

[0048] The operation panel 8 is formed on the upper shell 12. The control panel 8 includes an operation display interface 801, an on / off key 82, a temperature adjustment component 83 and an air volume adjustment key 84 from left to right. The on / off key 82 can be used to start and stop the portable hair dryer 1000. A button or a knob can be used. The temperature adjustment component 83 and the air volume adjustment key 84 can be used to adjust the temperature and the air volume respectively. The control panel can adjust the temperature and the air volume steplessly, so that the required air outlet temperature and the air volume can be adjusted in any temperature range and air volume range specified by it to meet the needs of blowing and drying different types of mats and mats with different moisture contents, or the control panel can adjust the air outlet temperature and the air volume in multiple gears, such as "setting high, medium and low gears" for different scenarios, with strong applicability. The operation interface 801 uses a liquid crystal display screen to display the temperature and air volume values, which is intuitive and clear at a glance.

[0049] A support frame 6 is fixedly or detachably connected to the lower shell 11 of the main unit 1. When the portable hair dryer 1000 is used, the main unit 1 is placed on the ground, and the support frame 6 can play a supporting role to prevent it from directly contacting the ground and being affected by water vapor. The support frame 6 can also be detachably connected to the lower shell 11 of the main unit 1. When the portable hair dryer 1000 is not in use, the support frame 6 under the main unit 1 can be disassembled and stored. A handle 5 is integrally formed above the upper shell 12. When the portable hair dryer 1000 is used, it can be lifted by hand and moved for easy operation. There is also a power plug 7 at the back of the main unit 1, which can be connected to a socket for power.

[0050] See also Figure 4The gas working module 13 includes a gas generator and a heating module 10. The gas working module 13 may also include a connecting pipe 14. The number of gas generators may be only one. The air outlet of the gas generator is connected to the connecting pipe 14. The air outlet duct of the connecting pipe 14 is connected to the flexible tube 3. The flexible tube is finally fluidly connected to the air outlet nozzle 4. Of course, the number of gas generators may be multiple. The present application exemplarily shows that the number of gas generators is two. The two gas generators are gas generator 1301 and gas generator 1302 respectively. The air outlets 1303 and 1304 of the two gas generators are arranged side by side and close together. The air outlets of the two gas generators are connected to the same air outlet duct 903 through pipes 901 and 902 of a two-way pipe (roughly in the shape of "trousers") 9; in this way, the wind generated by the two gas generators converges into one air duct, and the air volume is doubled. When the portable hair dryer generates hot air to blow and dry the mat, the blowing and drying efficiency is greatly improved and the air drying time is shortened. The number of gas generators can also be three, four or more. The wind generated by the gas generators is gathered into one air duct, which is connected to the same air duct through a multi-way pipe. The specific number of gas generators used depends on the actual situation, the type of the air-dried mat and the moisture content after cleaning.

[0051] See again Figure 2 and Figure 3 The gas generator is fixed on the mounting base 14, and the mounting base 14 is a semicircular support, and its circular through hole 1305 and circular groove 141 are fixedly connected by screws (the screws are not shown in the figure). The number of circular through holes 1305 is the same as the number of gas mounting bases 14. The gas generator passes through the gap of the mounting base 14 and is fixed by screws through the circular through hole 1305 and the circular groove 141. The fixing base 35 is then fixed to the left wall, right wall and rear wall of the lower shell 11 by screws. The circular through hole 1305 and the circular groove 1401 cooperate to fine-tune the air outlet angle of the gas generator, with high degree of freedom and good flexibility.

[0052] See also Fig.12 The heating module 10 includes a heater 101 and a mounting frame 102. The heater 101 can use a heating wire, which can quickly heat up. After the air fluid passes through the heating wire, hot air of the required temperature is quickly generated. The mounting frame 102 uses an impeller-type skeleton with four paddle blades. In this way, the fluid air generated by the gas generator encounters little obstruction when passing through the heating module 10, and the air outlet is smooth and the air outlet volume is basically unaffected.

[0053] The outlet of the two-way pipe 9 or the outlet of the multi-way pipe 9 is fluidly connected to the flexible pipe 3. After the gas passes through the multi-way pipe, the fluid path is short, the corner is small, the resistance is small, and the air volume is basically not lost. When the gas working module 13 generates hot air from the flexible pipe 3 and the air outlet 4 to blow and dry the mat, the flexible pipe 3 has flexibility and ductility, can be stretched and bent at will, and is easy to hold and move.

[0054] See also Figure 5 The air outlet nozzle 4 is fluidly connected to the air outlet of the flexible tube 3 through a quick-connect structure, so that a variety of different types of air outlet nozzles can be quickly replaced to suit different cushions. The quick-connect structure specifically adopts a clamping structure, in which the protrusion 31 on the flexible tube 3 is clamped and rotated with the clamping slot, and the air outlet nozzle 4 is sleeved on the air outlet of the flexible tube 3, and the protrusion on the flexible tube 3 is inserted into the notch 41 and enters the bottom to abut against each other, and the air outlet nozzle 4 is then rotated counterclockwise into the transverse groove 42, so that the quick connection is completed, and the air outlet nozzle will not fall out. When the air outlet nozzle needs to be replaced, the air outlet nozzle is rotated clockwise so that the protrusion 31 is aligned with the notch 41 to pull out the air outlet nozzle. Compared with the traditional threaded connection method, it can be clamped and rotated into place at one time, which saves time and effort. The traditional threaded connection requires the air nozzle to be rotated dozens of times before it can be connected to the flexible tube, and its replacement is time-consuming and labor-intensive.

[0055] See also Figure 6 The air outlet nozzle can be replaced with different types of air outlet nozzles, such as a flat air outlet nozzle 401, a multi-column rectangular air outlet nozzle 401, a conical air outlet nozzle 403 and a shower-shaped air outlet nozzle 404.

[0056] See also Figure 7 and Figure 8 A circumferential groove is recessed below the notch 41 and the transverse groove 42 on the inner wall of the air outlet nozzle 4, and a sealing ring 44 is recessed therein. Its outer diameter is larger than the inner diameter of the air inlet of the air outlet nozzle 4. When the air outlet nozzle 4 is connected to the air outlet of the flexible tube 3, the sealing ring 44 is tightly fitted with the outer wall of the outlet of the flexible tube 3 to deform and seal to prevent air leakage. The sealing ring 44 can be a rubber elastic sealing ring.

[0057] See also Fig. 9 and Fig.10 , see again Figure 1 The gas generator is connected to a silencer pipe 2 through a connecting pipe 9 and then to a flexible pipe 3. The silencer pipe 2 is large in the middle and small at both ends. When the gas generator generates air fluid, there will be a large noise. After the air fluid noise passes through the silencer pipe, it is reflected back and forth in the large cavity in the middle to reduce the noise. When the portable hair dryer 1000 is used to blow dry the mat, it is not so harsh.

[0058] See also Figure 12-14In the second exemplary embodiment of the present application, a dovetail groove 1101 is arranged below the host 1100, and the dovetail groove 1101 is a structure with a large inner part and a small outer part. A mounting plate 1103 is fixed on the wall 1104, and the mounting plate 1103 is fixed to the wall 1104 by glue or screws. The mounting plate 1104 is integrally formed with a dovetail protrusion 1102 that matches the shape of the dovetail groove 1101. The dovetail protrusion 1102 of the host 1 is sleeved on the dovetail protrusion 1102. When the portable hair dryer 100 is not in use, the host can be wall-mounted on the wall 1104 to avoid occupying too much floor space, and it is convenient to use and operate. The method of wall-mounting on the wall by the dovetail groove structure is simple and reliable compared with the form of plugging or rope binding. The dovetail groove structure is a simple and practical structure and is easy to form.

[0059] See also Fig.15 , see again Figure 1 The portable hair dryer 1000 also includes a controller, a control unit, a first current detection module, a second current detection module and a temperature sensor. The first current detection module, the second current detection module and the temperature sensor are electrically connected to the control unit. The gas working module 13 includes a gas generator and a heating module 10. The gas working module 13, the flexible tube 3 and the air outlet 4 are connected in sequence. The gas generator generates hot air after passing through the heating module 10, and the hot air is used to blow and dry the mat after passing through the flexible tube 3 and the air outlet 4.

[0060] The main unit 1 is placed on the ground, and the air outlet 4 is held in the hand. Due to the telescopic ductility of the flexible tube 3, the cleaned mat can be moved within a relatively long radius to blow and dry it; the first current detection module and the second current detection module are electrically connected to the control unit, the first current detection module is used to detect the current flowing through the gas generator, and the second current detection module is used to detect the current flowing through the heating module. The first current detection module and the second current detection module respectively feed back the current value passing through the gas generator and the current value of the heating module to the control unit, and the control unit controls the information in a predetermined form to prompt that the current is too large or too small, which is used to evaluate whether the currently working gas generator and heating module are working normally or whether there is an abnormality, so as to ensure the normal operation of the entire portable hair dryer. The current value passing through the gas generator and the current value of the heating module have a maximum current value and a minimum current value for normal operation, respectively. When the current is greater than or less than the maximum working current value and the minimum working current value of the gas generator and the heating module, respectively, the operation display panel of the upper shell 12 of the main unit 1 displays that the gas generator or the heating module is not working properly or abnormal, and can also be reminded by sound alarm or flashing light.

[0061] The temperature sensor used for temperature detection of the heating module 10 can be a PT100 or NTC sensor probe, and the temperature sensor is electrically connected to the control unit. The specific scheme for current detection of the heating wire 101 in the heating module 10 is to use an operational amplifier to collect the current change of the heating wire through a sampling resistor and feed it back to the control unit; the specific scheme for current detection of the gas generator is to use an AC transformer to sense the AC current and detect the current change and feed it back to the control unit. The first current detection module for detecting the current of the gas generator is the AC transformer, which adopts the DL-CT08CL2-1000 / 1 model AC transformer of Nanjing Xiangshang Electronics. The second current detection module for detecting the current of the heating wire is the operational amplifier, and the controller is the operation panel 8.

[0062] The control unit may include a memory for storing the current value of the gas generator detected by the first current detection module, the current value of the heating module detected by the second current detection module, the temperature value detected by the temperature sensor, and the like.
