Description
Technical Field
[0001] This utility model specifically relates to a dual-channel hair dryer thyristor module mounting structure. Background Technology
[0002] Hair dryers, as a common personal care appliance, primarily function by using a motor-driven fan to generate airflow and heating elements to heat the airflow, thereby achieving rapid hair drying. As users' demands for hair dryer performance continue to increase, especially regarding the precision of airflow control, temperature control stability, and the miniaturization and intelligence of the products, the layout of internal functional modules and thermal management design of hair dryers face greater challenges.
[0003] In existing technologies, most hair dryers adopt a single-duct structure, and their internal functional components typically include a motor, heating element, control circuit board, and various sensors. The high-power thyristor module (i.e., the silicon controlled rectifier module) used to control the on / off state of the motor or heating element is generally mounted on the circuit board and placed outside or at the edge of the duct. This arrangement has the following drawbacks: Firstly, the thyristor module generates a large amount of heat; if cooling is achieved solely through natural heat dissipation or additional heat sinks, the heat dissipation efficiency is low, easily leading to excessive temperature rise and affecting operational stability and lifespan. Secondly, this module often exists as an independent electronic component, not integrated into the structural layout, resulting in low internal space utilization and hindering the development of thinner and more compact products.
[0004] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dual-channel blower thyristor module mounting structure that improves compactness and heat dissipation performance.
[0006] This utility model is achieved through the following technical solution:
[0007] This utility model provides a dual-channel hair dryer SCR module installation structure, including a functional component disposed inside the hair dryer. The functional component has a partition structure that divides the inner cavity of the functional component into at least two through-flow air outlet channels. The partition structure has a notch area that connects the air outlet channels. The functional component contains a SCR module, which is located in the notch area and thus covers the notch area.
[0008] As described above, the dual-channel blower thyristor module mounting structure includes a module substrate, and thyristor elements are provided on both sides of the module substrate so that the two thyristor elements are respectively located in the two air outlet channels.
[0009] As described above, the dual-channel hair dryer SCR module mounting structure includes a heating housing and a motor housing with interconnected inner cavities. The motor housing has a partition platform that divides its inner cavity, and the heating housing has a heating baffle that divides its inner cavity and is correspondingly arranged with the partition platform. The heating baffle and the partition platform together constitute the partition structure, and the reserved gap between the partition platform and the heating baffle constitutes the notch area.
[0010] As described above, the dual-channel blower thyristor module mounting structure includes a motor housing comprising a symmetrically arranged upper housing and a lower housing, which together form a cavity. Both the upper and lower housings have protrusions facing each other. When the two housings are closed, the two protrusions connect to form the partition platform. The module base plate has an upper locking block on the upper side, a lower locking block on the lower side, and a rear locking block on the rear side. The upper housing has an upper locking groove for inserting the upper locking block, and the lower housing has a lower locking groove for inserting the lower locking block. The upper and lower housings have semi-enclosed grooves opposite to each other. When the two housings are closed, the two semi-enclosed grooves connect to form a rear locking groove for inserting the rear locking block.
[0011] As described above, in the dual-channel blower thyristor module mounting structure, the partition platform divides the inner cavity of the motor housing into two mounting cavities for mounting the motor. The mounting cavities form part of the air outlet channel, and the thyristor element is electrically connected to the motor in the same air outlet channel.
[0012] As described above, in the dual-channel blower SCR module mounting structure, the lower housing is provided with a first snap-fit groove, and the upper housing is provided with a first snap-fit protrusion that can snap into the first snap-fit groove.
[0013] As described above, in the dual-channel blower thyristor module mounting structure, the upper and lower parts of the heating housing are provided with second snap-fit grooves, and the upper and lower housings are provided with second snap-fit protrusions that can engage with the second snap-fit grooves.
[0014] In the dual-channel blower SCR module mounting structure described above, the SCR module is located on the front side of the mounting cavity.
[0015] Compared with the prior art, the thyristor module mounting structure provided by this utility model has the following advantages:
[0016] 1. Improve heat dissipation performance and enhance device reliability. By placing the thyristor module in the gap area between the two air outlet channels, the thyristor elements on both sides are exposed to high-speed airflow, achieving double-sided forced air cooling, significantly improving heat dissipation efficiency, reducing operating temperature rise, and extending the service life of power devices.
[0017] 2. The structure is highly integrated, saving space and costs. The original gap area in the partition structure is cleverly used to install the thyristor module, which can be used for both electrical control and internal cavity partitioning, achieving "one thing for multiple uses". This reduces the independent support structure, improves space utilization, and makes the whole machine structure more compact.
[0018] 3. Convenient and reliable assembly, conducive to mass production. It adopts a three-way snap-fit positioning and shell-to-shell snap-fit structure to achieve screwless and rapid installation of thyristor modules and functional components. The connection is stable and has good vibration resistance, which facilitates automated assembly and subsequent maintenance, and improves production efficiency and product consistency.

[0024] The utility model will be further described below with reference to the accompanying drawings:
[0025] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.
[0026] This embodiment describes a dual-channel blower SCR module mounting structure, such as... Figure 1 As shown, it includes a functional component 1 installed inside the hair dryer A. Functional component 1 mainly houses components such as a motor for generating airflow, a heating device for heating the airflow, a control module, and sensors. Figures 2 to 5As shown, the functional component 1 has a partition structure 11 that divides the inner cavity of the functional component 1 into at least two through-flow air outlet channels 10. The partition structure 11 has a notch area 101 connecting the air outlet channels 10. The functional component 1 has a silicon controlled rectifier (SCR) module 12 located in the notch area 101, thus covering the notch area 101. Through the above structure, the SCR module 12 serves to partition the inner cavity. That is, the SCR module 12 and the partition structure 11 together divide the inner cavity of the functional component 1. This saves space and makes the product structure more compact. Secondly, the SCR module 12 is located between the two air outlet channels 10, allowing the SCR module 12 to dissipate heat through the airflow of the air outlet channels 10 on at least two sides, improving the energy efficiency of the product. This structure, by setting a partition structure 11 inside the functional component 1 to form two independent air outlet channels 10, realizes a dual-airflow design, which is suitable for high-end hair dryers that require independent control of airflow or air temperature. The partition structure 11 is not completely enclosed, but rather has a pre-reserved gap area 101, which was originally intended for structural connections or assembly. This innovative design places the thyristor module 12, originally used only for electrical control, within this gap area 101. This allows it to perform circuit control functions while physically filling and sealing the gap, thus participating in airflow separation within the cavity. This "multi-purpose" design concept achieves structural integration and functional versatility, significantly improving space utilization and thermal management efficiency.
[0027] As a preferred embodiment, the thyristor module 12 includes a module substrate 121. Thyristor elements 122 are provided on both sides of the module substrate 121, such that the two thyristor elements 122 are respectively located in the two air outlet channels 10. The thyristor element 122, also known as a thyristor module, is a high-power semiconductor device mainly used to control the conduction and cutoff of current. It is soldered onto a circuit board substrate, i.e., onto the module substrate 121, and connected to the circuitry of the blower to achieve the control function. In this embodiment, the entire thyristor module 12 is arranged in the gap area 101 between the two air outlet channels 10, while the two thyristor elements 122 are respectively located in the two air outlet channels 10, greatly improving its heat dissipation efficiency. Furthermore, motors B can be arranged in the two air outlet channels 10 respectively, and the thyristor elements 122 located in the same air outlet channel 10 independently control the motor B in the same air outlet channel 10. Preferably, the thyristor module 12 can be located on the front side of the motor B, i.e., the air outlet side. The thyristor elements 122 are symmetrically arranged on both sides of the module substrate 121, exposing them to two air outlet channels 10. This allows the high-speed airflow to directly wash over the element surface, forming double-sided forced convection cooling. Compared to traditional methods that rely solely on single-sided natural heat dissipation or passive heat sinks, this structure significantly enhances the efficiency of the heat conduction path, effectively reduces the junction temperature of the thyristor during operation, and improves device lifespan and system stability. Simultaneously, by placing the thyristor module 12 on the air outlet side of the motor B, it can utilize the cooler airflow behind the motor, which has not yet been heated, for initial cooling, further optimizing thermal management performance.
[0028] In detail, such as Figure 4 and Figure 5 As shown, the functional component 1 includes a heating housing 13 and a motor housing 14 with interconnected internal cavities. The motor housing 14 has a partition platform 141 that divides its internal cavity. The heating housing 13 has a heating baffle 131 that divides its internal cavity and is correspondingly positioned to the partition platform 141. The heating baffle 131 and the partition platform 141 together constitute the partition structure 11. The reserved gap between the partition platform 141 and the heating baffle 131 constitutes the notch area 101. The heating housing 13 and the motor housing 14 respectively perform heating and driving functions. Through the precise alignment of the partition platform 141 and the heating baffle 131, a continuous and stable partition structure 11 is formed. The notch area 101 between them not only provides installation space for the thyristor module 12 but also ensures the continuity and sealing of the airflow channel, avoiding airflow interference. This design achieves a unified functional zoning and structural integration, facilitating modular assembly and subsequent maintenance.
[0029] In detail, such as Figure 4 and Figure 5As shown, the motor housing 14 includes an upper housing 142 and a lower housing 143 symmetrically arranged, which together form a cavity. Both the upper housing 142 and the lower housing 143 have protrusions 144 facing each other. When closed, the two protrusions 144 connect to form the partition platform 141. The module base plate 121 has an upper locking block 123 on its upper side, a lower locking block 124 on its lower side, and a rear locking block 125 on its rear side. The upper housing 142 has an upper locking slot 145 for inserting the upper locking block 123, and the lower housing 143 has a lower locking slot 146 for inserting the lower locking block 124. The upper housing 142 and the lower housing 143 have semi-enclosed grooves opposite each other. When closed, the two semi-enclosed grooves connect to form a rear locking slot 147 for inserting the rear locking block 125. This mechanism makes the installation of the thyristor module 12 more convenient and stable. The system employs a three-way snap-fit positioning structure (upper snap-fit block 123, lower snap-fit block 124, and rear snap-fit block 125 in conjunction with upper snap-fit slot 145, lower snap-fit slot 146, and rear snap-fit slot 147), achieving three-dimensional limiting installation of the SCR module 12. This effectively prevents displacement or loosening of the module during vibration or thermal expansion and contraction, improving the reliability of the electrical connection. Furthermore, this snap-fit structure eliminates the need for additional fasteners (such as screws), simplifying the assembly process, increasing production efficiency, and meeting the demands of automated assembly in modern home appliances.
[0030] In detail, such as Figure 4 and Figure 5 As shown, the lower housing 143 is provided with a first snap-fit groove 1431, and the upper housing 142 is provided with a first snap-fit protrusion 1421 that can engage with the first snap-fit groove 1431, so that the two housings can be easily assembled into a motor housing 14. Through the cooperation of the first snap-fit groove 1431 and the first snap-fit protrusion 1421, the upper housing 142 and the lower housing 143 can be quickly locked together. The structure is simple, the connection is reliable, and it is easy to disassemble and maintain, while avoiding irreversible assembly problems caused by gluing or welding.
[0031] In detail, such as Figure 4 and Figure 5 As shown, the heating housing 13 has a second snap-fit groove 132 on both its upper and lower parts, and the upper housing 142 and lower housing 143 both have a second snap-fit protrusion 149 that can engage with the second snap-fit groove 132. This allows the motor housing 14 and the heating housing 13 to be easily and securely connected. Through the cooperation of the second snap-fit groove 132 and the second snap-fit protrusion 149, a modular connection between the motor housing 14 and the heating housing 13 is achieved, making the entire functional component 1 a structurally complete and airtight whole. This connection method not only improves the overall structural strength of the machine, but also facilitates step-by-step assembly and testing on the production line, improving the flexibility of the manufacturing process and the yield rate.
[0032] In summary, this technical solution has the following significant advantages: Compact structure and high space utilization: Integrating the thyristor module 12 into the notch area 101 of the partition structure 11 achieves a dual function of "function + structure," reducing additional support components and shrinking the overall size. Highly efficient heat dissipation, improving energy efficiency and lifespan: The thyristor element 122 is exposed to high-speed airflow on both sides, achieving forced air cooling, significantly reducing operating temperature and improving the reliability of power devices. Modular design for easy assembly and maintenance: Multiple sets of snap-fit structures enable quick connection between the housing and the module, eliminating the need for screws and making it suitable for automated production. Dual-channel independent control and strong functional expandability: Each air outlet channel 10 can be configured with an independent motor and thyristor control, supporting differentiated airflow and temperature adjustment, suitable for high-end intelligent hair dryers. Stable structure and good vibration resistance: Three-way snap-fit positioning ensures the thyristor module 12 remains stable under complex operating conditions, avoiding poor contact or electrical faults.
