[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.
[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] This utility model provides a household magnetic fascia handle, such as Figures 1-3As shown, the device includes an upper cover 1 and a lower cover 2, which together form a housing 3. Inside the housing 3, a cable 4, a ducted fan 5, and a magnetic therapy coil 6 are arranged sequentially from one end to the other. There is a gap between the cable 4 and the housing 3 to form an air inlet 31. An air outlet 11 formed by several through holes is opened in the area of the upper cover 1 corresponding to the magnetic therapy coil 6. The magnetic therapy coil 6 drives the external airflow to enter the housing 3 from the air inlet 31 and then flows out of the housing 3 from the air outlet 11 after passing through the magnetic therapy coil 6.
[0023] In this embodiment, the upper cover 1 and the lower cover 2 are made of heat-resistant plastic and are connected by a snap-fit structure with matching protrusions and slots to form a hollow shell 3. The shell 3 is generally long and rod-shaped, and a cable 4 is installed at its tail end through the limiting and compacting structure of the upper cover 1 and the lower cover 2. A data connector is provided at the end of the cable 4 away from the handle. The data connector is used to insert into the socket of the magnetic therapy host (not shown in the figure), so that the handle can be electrically connected to the magnetic therapy host. The magnetic therapy coil 6 is installed at the head of the shell 3 through the limiting structure to generate a high-energy focused pulse magnetic field, which acts on the nervous system of the fascia area of the body, thereby producing a magnetic therapy effect. Multiple fan-shaped through holes are opened on the top surface of the upper cover 1 at the position corresponding to the magnetic therapy coil 6. The diameter of the through holes is about 1-1.5 mm, and the fan-shaped through holes form an air outlet 11. A ducted fan 5 is fixedly installed inside the housing 3, slightly near its rear, using screws or snap-fit mechanisms. The ducted fan 5 is driven by a high-speed brushless DC motor with a speed between 21000±10% RPM and 100000±10% RPM. Its speed can be controlled within this range according to the heat dissipation requirements of the magnetic therapy coil 6, allowing for rapid heat dissipation. The air duct wall inside the housing 3 adopts an arc-shaped structure to reduce airflow resistance and improve heat dissipation. The magnetic therapy coil 6 also adopts an arc-shaped shape, allowing airflow to smoothly surround the entire coil, effectively dispersing heat and achieving optimal air-cooling efficiency.
[0024] This invention improves the heat dissipation performance of the handle and enhances the user experience by incorporating an air inlet 31, a ducted fan 5, a magnetic therapy coil 6, and an air outlet 11 inside the housing 3. The ducted fan 5 drives external airflow to enter the housing 3 through the air inlet 31 and exit the housing 3 through the air outlet 11 after passing through the magnetic therapy coil 6.
[0025] Furthermore, the magnetic therapy coil 6 is wound outward from the middle of its main length, with one end wound clockwise from the middle and the other end wound counterclockwise from the middle, so that the wire ends of the magnetic therapy coil 6 are on the outermost coil of the uppermost layer and the outermost coil of the lowermost layer, respectively.
[0026] like Figures 4-6As shown, the magnetic therapy coil 6 can be wound using one, two, or more wire tubes composed of multi-strand enameled wire. It can be wound in one or more layers, or in single or multiple turns, depending on actual needs. In this embodiment, the magnetic therapy coil 6 is wound using two wire tubes, with five turns and four layers. This winding method achieves the smallest volume and flattest top and bottom surfaces for coils of the same wire length, unlike typical coils (refer to the coil disclosed in CN112582159A) where the lead wire at one end extends outwards from the innermost coil, crossing half the coil length. The magnetic therapy coil 6 of this invention provides a high-energy, low-heat-generating, high-energy focused pulsed magnetic field.
[0027] Furthermore, a silicone bracket 32 is fitted inside the housing 3 to reduce noise generated by the vibration of the ducted fan 5. The silicone bracket 32 is fitted into the ducted fan 5.
[0028] like Figure 3 As shown, the silicone bracket 32 is annular in shape, and its internal through-hole is sized to tightly fit and fix the ducted fan 5 around its perimeter. The silicone bracket 32 has multiple slots around its perimeter for fitting with protrusions distributed on the upper cover 1 and lower cover 2, thus securing it firmly inside the housing 3. The silicone bracket 32 has high elasticity, which reduces the amplitude of vibration when the ducted fan 5 rotates at high speed, thereby reducing noise and improving the user experience.
[0029] Furthermore, the end of the housing 3 is provided with a buffer sleeve 7 for protecting the cable 4 and a locking sleeve 8 for locking the buffer sleeve 7 onto the housing 3; the locking sleeve 8 covers the buffer sleeve 7 and is detachably connected to the housing 3; the buffer sleeve 7 covers the cable 4.
[0030] like Figure 3 As shown, the locking sleeve 8 is screwed onto the tail of the housing 3 via a threaded connection, and the thicker end of the buffer sleeve 7 is clamped between the locking sleeve 8 and the tail of the housing 3. The buffer sleeve 7 can be a rubber corrugated sleeve or a flexible spring sleeve, which can prevent the connection between the cable 4 and the housing 3 from being excessively and repeatedly bent, and prevent the internal conductive core from being broken, thus affecting the normal use of the handle.
[0031] Furthermore, the locking sleeve 8 is provided with a dustproof mesh 81 to prevent dust from entering the interior of the housing 3 from the air inlet 31.
[0032] like Figure 3As shown, the lock sleeve 8 is fitted with a buffer sleeve 7, and there is a certain gap between the two to allow external airflow to communicate with the air inlet 31. The dustproof net 81 is a ring-shaped dustproof net with a notch (similar to the notch of a spring washer). The dustproof net 81 can be installed inside the lock sleeve 8 by prying open the notch. The dustproof net 81 is also fitted with the buffer sleeve 7, thus preventing larger particles such as dust and lint from entering the housing 3, ensuring good heat dissipation for the handle. The notched dustproof net 81 makes it easy for users to replace or clean.
[0033] Furthermore, the housing 3 is equipped with a button panel assembly 33 for adjusting the intensity of magnetic therapy.
[0034] like Figure 3 As shown, the button panel assembly 33 includes three buttons 331 and a button panel 332. The three buttons 331 are a "+" button for increasing the intensity of magnetic therapy, a "-" button for decreasing the intensity of magnetic therapy, and a "switch" button for activating the handle.
[0035] Furthermore, a temperature sensor 61 is provided on the surface of the magnetic therapy coil 6. The temperature sensor 61 is used to detect the temperature of the magnetic therapy coil 6 and acts as a temperature switch. It is connected to the magnetic therapy coil 6 and / or the ducted fan 5 through an external magnetic therapy host. When the temperature of the magnetic therapy coil 6 is detected to be higher than the preset temperature, the power supply circuit of the magnetic therapy coil 6 is cut off or the speed of the ducted fan 5 is increased.
[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
