Description

An electric powder dispenser Technical Field

[0001] This invention relates to the field of powder dispenser technology, and more specifically to an electric powder dispenser. Background Technology

[0002] Existing powder dispensers for dense hair fibers use a design similar to a peppercorn cap, requiring manual shaking of the bottle for dispensing. This method results in uneven powder distribution, with some areas receiving more powder than others, affecting visual appeal and causing excessive fiber accumulation. Manual air-filled dispensers require constant finger pressure, leading to inconsistent powder output. For patients with large areas of sparse hair, prolonged pressure is necessary to cover the entire sparse area, making it time-consuming and laborious. Existing electric powder dispensers have a small, top-mounted switch that is inconvenient for one-handed operation, hindering accurate start-stop. Furthermore, existing dispensers cannot be configured for different powder volumes. While a nozzle plug is included, it is bulky when plugged, making it difficult to carry. If the nozzle is removed, the lack of a plug allows powder to leak out through the opening. Summary of the Invention

[0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide an electric powder dispenser, which solves the problems of existing powder dispensers, such as inconvenience of manual powder dispensing, uneven powder dispensing, inability to adjust the powder dispensing amount, no place to put the nozzle plug which is easy to lose, and easy powder leakage when not in use. Technical solution

[0004] To solve the above problems, the technical solution provided by the present invention is as follows:

[0005] An electric powder dispenser includes a nozzle body, an air inlet on one side of the nozzle body, and an air outlet on the other side corresponding to the air inlet. A nozzle surround is provided on the outer surface of the air outlet, and the nozzle is inserted into the air outlet through the nozzle surround. The nozzle has a nozzle protrusion inside the air outlet. A right spray button and a left spray button are respectively provided on both sides of the air inlet and the air outlet of the nozzle body. A material tank is connected to the bottom of the nozzle body. A motor base is provided on one side of the air inlet inside the nozzle body, and a motor is provided in the motor base. A nozzle plug is also provided on the nozzle body.

[0006] Furthermore, the nozzle has a flat nozzle structure.

[0007] Furthermore, the nozzle body is provided with a plug receiving groove, which is a closed structure. The nozzle plug is placed in the plug receiving groove. The nozzle plug consists of a two-stage stepped structure. The size of the first-stage nozzle plug is the same as the opening size of the nozzle surround. The first-stage structure of the nozzle plug can block the nozzle surround. The size of the second-stage nozzle plug is the same as the opening of the air outlet port of the nozzle. The second-stage structure of the nozzle plug can block the air outlet port of the nozzle.

[0008] Furthermore, the motor base is provided with an annular double-layer channel, which consists of an inner channel and an outer channel. The outer channel is connected to the air inlet and is equipped with a filter screen.

[0009] Furthermore, the inner channel is isolated from the outer channel. The motor is installed inside the inner channel, and a motor bushing is provided outside the motor. The motor and the motor bushing are installed on the side of the inner channel near the material tank.

[0010] Furthermore, the motor is provided with a fan blade on the side facing the material tank, and the fan blade is arranged corresponding to the opening of the outer channel facing the material tank.

[0011] Furthermore, the air inlet is formed by a number of regularly arranged through holes.

[0012] Furthermore, a battery is provided inside the motor body, and a battery charging port is provided on the nozzle body, with a battery port plug blocking the outside of the battery charging port.

[0013] Furthermore, a control panel is also provided inside the nozzle body.

[0014] Furthermore, the nozzle body is provided with a top cover, the top cover is provided with a power button, and a light-transmitting plate is provided between the top cover and the power button. Beneficial effects

[0015] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0016] The technical solution provided by this invention uses an electric motor drive to ensure stable airflow, thereby enabling dense hair fibers to be blown out evenly and smoothly, improving efficiency, stability, and convenience. Furthermore, the powder dispenser of this invention is equipped with spray buttons on both sides of the nozzle body, which can further improve the efficiency and convenience of use. It also features a nozzle protrusion to make the powder sprayed from the nozzle more uniform and prevent clumping. The circuit controls the motor speed and precisely adjusts the airflow to provide continuous and stable airflow, significantly improving the powder output and efficiency.

[0017] 1. Our technology uses an electric motor to ensure stable airflow, allowing the hair-enhancing fibers to be blown out evenly and smoothly. This method overcomes the instability of manual operation, avoids uneven distribution and accumulation of hair-enhancing fibers, and improves efficiency and convenience.

[0018] 2. This invention controls the motor speed through circuitry, precisely adjusts the airflow, and provides continuous and stable airflow, significantly improving powder output and efficiency, and solving the problems of unsatisfactory powder output and inability to continuously output powder in traditional methods.

[0019] 3. This design adds three powder dispensing levels, allowing users to choose the appropriate level based on the area to be used. For example, a low powder dispensing level can be used on the hairline, a medium level on the parting area, and a high level on large, sparse areas (such as the bald patch on the crown), ensuring precise and effective powder dispensing for different areas. Additionally, as the amount of powder used decreases and the powder in the bottle diminishes, a higher powder dispensing level can be used to facilitate smooth powder dispensing.

[0020] 4. Our innovative design uses a cylindrical shape, which makes the powder dispenser smaller and more convenient to carry.

[0021] 5. Traditional spray nozzles are mainly round, with small powder outlets and low efficiency. We have optimized the nozzle design and changed it to a flat nozzle to improve powder output efficiency.

[0022] 6. This design features silicone start / stop buttons on both sides of the nozzle, allowing you to stop powder dispensing at any time, making operation simple and convenient.

[0023] 7. We have optimized the nozzle plug design. When carrying the product, the nozzle can be removed and the plug can be used to seal the nozzle orifice, making it convenient to carry, reducing space usage, and preventing powder leakage. Simultaneously, when the product is not in use, the nozzle plug can seal the nozzle to prevent water vapor from entering the bottle and causing fibers or powder to clump. This dual-purpose plug is convenient, efficient, and reduces costs. Attached Figure Description

[0025] Figure 2 is a cross-sectional view of the internal structure of Embodiment 1 of the present invention;

[0026] Figure 3 is an exploded view of Embodiment 1 of the present invention. Detailed Implementation

[0027] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0028] Referring to Figures 1-3, an electric powder dispenser is mainly used in conjunction with hair thickening fibers to allow the fibers to be sprayed evenly, adhered to the hair strands, and cover the sparse areas on the top of the head of hair loss patients to achieve a visually thicker effect.

[0029] The electric powder dispenser includes a nozzle body 9, which contains components for spraying dense hair fibers. A material tank 17 is connected to the bottom of the nozzle body 9 for storing dense hair fibers. Both the nozzle body 9 and the material tank 17 are cylindrical structures, making them easy to carry and use.

[0030] A nozzle 18 is provided on one side of the nozzle body 9, and an air inlet 21 is provided on the other side. The air inlet 21 is formed by a number of regular through holes arranged evenly on the outer shell of the nozzle body 9. A motor base 13 is provided inside the nozzle body 9 near the air inlet 21 and communicates with the air inlet 21. An annular double-layer channel is provided inside the motor base 13 near the air inlet 21. The channel outside the annular double-layer channel inside the motor base 13 is used to communicate with the material tank 17.

[0031] The annular double-layer channel is divided into an inner channel and an outer channel, which are isolated from each other. The outer channel is connected to the air inlet 21. Air entering from the air inlet 21 will directly enter the outer channel. A motor bushing 12 is installed inside the inner channel. The motor bushing 12 is wrapped around the motor 14 and installed together in the inner channel. The motor 14 has a fan blade 16 facing the material tank 17. When the fan blade 16 rotates, it is in a blowing state facing the material tank 17. When the fan blade 16 rotates, it is in a suction state facing the annular double-layer channel. The fan blade 16 is set to correspond to the opening of the outer channel of the annular double-layer channel facing the material tank 17, so that the suction force of the fan blade 16 is transmitted to the air inlet 21 through the outer channel, so that the air inlet 21 can attract the air outside the air inlet 21 on the nozzle body 9.

[0032] The outer channel is equipped with a filter screen 11. The air inlet 21 can initially filter larger foreign objects, while the filter screen 11 can filter smaller impurities, preventing impurities from entering the material tank 17. This prevents impurities from clogging the nozzle 18 or spraying onto the user's hair with the powder when using the powder dispenser, causing discomfort to the user and affecting the user's experience.

[0033] The motor mount 13 is fixed inside the nozzle body 9 by a surrounding fixing screw 15.

[0034] The motor 14 drives the fan blade 16 to rotate. The rotation of the fan blade 16 generates suction in the direction of the air inlet 21. The fan blade 16 draws air through the air inlet 21 into the outer channel of the annular double-layer channel. The air that enters the outer channel is blown into the material tank 17 after passing through the fan blade 16.

[0035] The fan blade 16 is positioned on the side away from the air outlet 22 to reduce internal airflow disturbance and to guide the airflow generated by the rotation of the fan blade 16 more effectively to the air outlet 22.

[0036] A battery compartment is provided on the side of the motor base 13 away from the air inlet 21. A battery 7 is provided in the battery compartment, and the battery 7 provides power to all electrical components in the powder generator.

[0037] The nozzle body 9 has an air outlet 22 for mounting the nozzle 18 on one side. The air outlet 22 is set to correspond to the air inlet 21. The nozzle 18 is inserted into the air outlet 22. The air outlet 22 is surrounded on the outer surface of the air outlet 22 of the nozzle body 9. The nozzle surround 221 is provided on the nozzle body 9. The nozzle surround 221 can easily install the nozzle 18 and insert the nozzle 18 into the air outlet 22. When the nozzle 18 is inserted into the air outlet 22, one end of the nozzle 18 protrudes from the plane of the air outlet 22 inside the nozzle body 9. The nozzle 18 has a nozzle protrusion 181 at the position of the nozzle protruding from the nozzle body 9 inside the air outlet 22. In the absence of the nozzle protrusion 181, similar powder dispenser products will tilt at a certain angle during normal use. When the fan blades rotate, some powder in the material tank, besides flying towards the air outlet with the airflow, will also rise upwards along the inner wall of the material tank towards the air outlet under the action of the internal rotating airflow, and then be directly sprayed out through the nozzle 18. This can lead to uneven powder discharge, or even powder clumping or lumps. After the nozzle 18 is provided with a nozzle protrusion 181 inside the nozzle body 9, the powder inlet port of the nozzle 18 (located on the side of the air inlet 22) will protrude a certain height from the inner wall of the body. This effectively prevents the powder that rises along the inner wall of the material tank from directly entering the nozzle. Only the powder carried by the airflow in the material tank 17 can be sprayed out through the nozzle 18, making the sprayed powder more uniform and preventing lumps.

[0038] The material tank 17 is filled with dense hair fiber powder 25. The powder 25 is driven by the airflow generated by the rotation of the fan blade 16, thereby carrying the dense hair fiber powder 25 into the nozzle 18 and spraying it out through the nozzle 18. The powder in the material tank 17 can also be replaced with other types of powder. In order to meet the application of the powder dispenser in other fields, the material tank 17 is not only used to store dense hair fiber powder, but can also be filled with other powders to directly serve as a powder dispenser. For example, chocolate powder, matcha powder or other powders can be put into the material tank 17 for use in food preparation, sterilization and other fields.

[0039] The nozzle 18 has a gradually converging structure from the powder inlet port to the powder outlet port. The nozzle 18 is set as a flat powder outlet at the powder outlet port. The flat powder outlet can improve the powder outlet efficiency, and the nozzle 18 also makes it convenient for users to control the powder outlet range.

[0040] The nozzle body 9 is also provided with a plug receiving groove 24, in which a nozzle plug 19 is installed. The nozzle plug 19 has a stepped structure, consisting of two stepped structures fixed as one unit. The two structures have different dimensions. The size of the first-stage nozzle plug is the same as the opening size of the nozzle surround 221, and the first-stage structure of the nozzle plug can directly block the opening of the nozzle surround 221. The size of the second-stage nozzle plug is the same as the opening of the air outlet port of the nozzle 18, and the second-stage structure of the nozzle plug can directly block the outlet of the nozzle 18. The plug receiving groove 24 is a closed partial groove, used only for installing the nozzle plug 19. When the user is not using the powder dispenser, the nozzle plug 19 can be installed on the opening of the powder outlet port of the nozzle 18 to block the nozzle 18, or... Users can also plug the nozzle plug 19 to block the opening of the nozzle surround 221 of the air outlet 22. Using the nozzle plug 19 allows for two types of clogging of the powder dispenser, suitable for different situations. Closing the powder outlet port of the nozzle 18 is suitable for clogging when the dispenser is stationary. Closing the nozzle surround 221 after removing the nozzle 18 is suitable for carrying the product. Existing nozzles do not have matching nozzle plugs for carrying. Since this product is frequently carried around, the addition of the nozzle plug allows the nozzle to be removed and the nozzle outlet hole plugged, making it convenient to carry, reducing space usage, and preventing powder leakage. Simultaneously, when the product is stationary, the nozzle plug can be used to prevent water vapor from entering the bottle and causing fiber or powder clumping. This dual-purpose plug is convenient, efficient, and cost-effective.

[0041] Inside the nozzle body 9, on the upper side of the motor base 13, there is a control board 5. Above the control board 5 is a top cover 2, which is installed on the top of the nozzle body 9. The top cover 2 is equipped with a power button 1, and the control board 5 is equipped with a power switch 23. The power button 1 and the power switch 23 are correspondingly arranged. The power button 1 and the power switch 23 are electrically connected to the control board 5 through the power switch 23. The user can directly control the control board 5 by pressing the power button, thereby enabling the power switch 23 to control the control board 5.

[0042] A light-transmitting element 3 is also provided between the top cover 2 and the control board 5. The light-transmitting element 3 is electrically connected to the control board 5 and is configured in conjunction with the power button 1. The light-transmitting element 3 is equipped with status LED beads. The light-transmitting element 1 transmits different states to the powder dispenser through the control board 5, thereby coordinating to make different LED beads light up. The LED beads can be selected as battery power indicator beads, power on / off LED beads, charging status indicator beads, air volume indicator beads, etc., depending on the status they are used to indicate.

[0043] The nozzle body 9 is located on both sides of the nozzle 18 and is equipped with a right spray button 10 and a left spray button 20 respectively. Both the right spray button 10 and the left spray button 20 are equipped with spray switches 6. The spray switches 6 are electrically connected to the control board 5. At the same time, the control board 5 is also electrically connected to the battery 7 and the motor 14.

[0044] The control board 5 is fixed inside the nozzle body 9 by the control board fixing screws 4.

[0045] By setting spraying buttons on both sides of the nozzle body 9 to control the powder output, the powder output can be started and stopped at any time. The operation is simple and convenient. This solves the problem that the switch button of the existing electric powder output is located on the top of the nozzle, the button is small, and it is inconvenient to press accurately with one hand during use, so it is impossible to start and stop the nozzle in time.

[0046] The nozzle body 9 is also provided with a battery charging port, and a battery port plug 8 is provided outside the battery charging port. The battery charging port is used to charge the battery 7, and the battery port plug 8 is used to block the battery charging port when not charging to prevent damage to the battery charging port.

[0047] The powder dispenser can also be set with multiple spray modes, preferably with three powder dispensing levels. Users can choose the appropriate level based on the area to be used, such as a low powder dispensing level for the hairline, a medium powder dispensing level for the parting area, and a high powder dispensing level for large areas of sparse powder (such as the bald patch on the crown of the head), to accurately and effectively dispense powder to different areas. At the same time, as the amount of powder used decreases and the powder in the bottle decreases, a higher powder dispensing level can be used to help with smooth powder dispensing.

[0048] When in use, press and hold the power button 1 to turn on the power, then press either the left or right spray button to start the motor 14 and drive the fan blade 16 to rotate, blowing the outside air through the air inlet 21 and the filter screen 11 towards the fiber powder in the material tank 17. The airflow carries the fiber powder and sprays it out through the nozzle 18 of the air outlet 22.

[0049] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
