Description

Technical Field

[0001] This utility model relates to the fields of electrical appliances and noise reduction technology, and more specifically, to a quiet high-speed water blower. Background Technology

[0002] With the rapid development of the pet industry, the demand for pet grooming is increasing, and the performance requirements for pet dryers are also constantly rising. There is an urgent need in the market for pet grooming equipment that combines efficient drying capabilities with low noise levels to meet pet owners' dual needs for a superior grooming experience and pet comfort, thereby driving technological upgrades in pet grooming tools.

[0003] Traditional pet dryers generally suffer from significant noise levels during use. The vibrations generated by the fan are transmitted through the machine body, exacerbating noise pollution and easily causing stress reactions in pets. Cats are particularly sensitive to noise, and many individuals react violently to currently used high-speed dryers, leading to a prolonged absence of bathing. Furthermore, some devices suffer from low drying efficiency, and their heating and cooling systems are poorly designed, resulting in long drying times and unstable temperature control, affecting safety and the pet's experience. The structural fixing methods also lack flexibility, making maintenance and cleaning inconvenient.

[0004] Therefore, it is necessary to design a quiet, high-speed water dryer to solve the problems of existing technologies, such as high noise levels that can cause stress to pets, low drying efficiency, unreasonable heating and heat dissipation leading to long drying times and unstable temperatures, and inflexible structural fixing methods that make maintenance and cleaning inconvenient. Utility Model Content

[0005] In view of this, this utility model proposes a quiet high-speed water blower, which aims to solve the problems of high noise and low drying efficiency of traditional equipment.

[0035] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a quiet high-speed water dryer by suspending the fan casing in the air with a fixing strap, reducing vibration-transmitted noise. Simultaneously, the first air inlet and outlet ducts at both ends of the fan casing are made of flexible material, and are sealed to the second air inlet and outlet ducts. This ensures soft contact between the fan casing and the box body, thereby reducing vibration, and the sealed design further reduces wind noise. Combined with a ventilation soundproofing device, noise is further reduced, creating a quiet environment and reducing pet stress. The high-speed operation of the fan, combined with the air inlet and outlet ducts, forms an efficient airflow channel. This, along with rapid heating with heating wires and timely heat dissipation with heat sinks, achieves high-speed drying with stable temperature. All components, such as the fan, fixing straps, and clips, are detachable for easy maintenance and cleaning. The heat dissipation base and heat sink design improve heat dissipation efficiency and ensure safe use. The overall structure balances noise reduction, high efficiency, safety, and convenience, optimizing the pet grooming experience. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] Reference Figure 1-4 As shown in some embodiments of this application, a quiet high-speed water blower includes:

[0047] The box body includes a lid 100 and a body 200, and the lid 100 and the body 200 are detachably connected.

[0048] The fan housing 300 is located inside the box body 200;

[0049] The fan 400 is located inside the fan housing 300, and the fan 400 is detachably connected to the fan housing 300.

[0050] A fixing strap is installed inside the box body 200. The fixing strap is detachably connected to the outer side of the fan housing 300. The fan housing 300 is suspended inside the box body 200 by the fixing strap.

[0051] Preferably, the fan housing 300 is arranged horizontally inside the box body 200; the fan 400 is arranged horizontally inside the fan housing 300; and the fixing strap is arranged vertically inside the box body 200.

[0052] Specifically, the lid 100 and the body 200 are opened and closed by threads and screws; the fan housing 300 is fixed inside the body 200, and its size is adapted to the inner cavity of the body 200; the fan 400 is installed inside the fan housing 300 and is fixed by detachable structures such as screws or buckles; the fixing strap is a flexible strip, which makes the fan housing 300 suspended in the air.

[0053] Understandably, the detachable connection between the cover 100 and the body 200 allows for quick disassembly during maintenance and cleaning, facilitating the removal of accumulated hair and dust and preventing debris buildup from affecting equipment performance or causing malfunctions. The fan housing 300, located inside the body 200, provides a stable mounting platform for the fan 400. The detachable connection between the fan 400 and the housing 300 allows for individual disassembly and maintenance of the fan 400, eliminating the need to replace the entire unit when the fan malfunctions, thus reducing maintenance costs.

[0054] Understandably, the fixing strap is detachably connected to the outer side of the fan housing 300, suspending the fan housing 300 above the box body 200. This suspended structure cuts off the path of vibration transmitted from the fan during operation to the box body—the vibration generated by the high-speed operation of the fan 400 is effectively buffered by the flexible material of the fixing strap, avoiding the transmission of structural vibration noise caused by rigid contact. For pet grooming scenarios, reduced noise can significantly reduce pet stress responses, making them more cooperative during drying and improving the grooming experience. In addition, the suspended design also allows airflow space around the fan housing 300, aiding in internal heat dissipation and indirectly improving the stability and lifespan of the fan.

[0055] In some embodiments of this application, it also includes:

[0056] The first air inlet duct 310 is located at one end of the fan housing 300, and the first air inlet duct 310 is made of flexible material;

[0057] The first air outlet duct 320 is located at the other end of the fan housing 300, and the first air outlet duct 320 is made of flexible material.

[0058] Preferably, the first air inlet duct 310 is arranged horizontally at one end of the fan housing 300; the first air outlet duct 320 is arranged horizontally at the other end of the fan housing 300.

[0059] In some embodiments of this application, it also includes:

[0060] The second air inlet duct 210 is located on the side of the box body 200, and the first air inlet duct 310 is sealed to the second air inlet duct 210.

[0061] The second air outlet 220 is located on the other side of the box body 200, and the first air outlet 320 is sealed to the second air outlet 220.

[0062] Specifically, the inner diameters of the first air inlet duct 310 and the first air outlet duct 320 are the same as the inner diameter of the fan 400. The first air inlet duct 310 is connected to one end of the fan housing 300, serving as the air intake channel of the fan 400. The first air outlet duct 320 is connected to the other end of the fan housing 300, serving as the air outlet channel of the fan 400. The second air inlet duct 210 and the second air outlet duct 220 are respectively located on both sides of the housing 200, communicating with the outside world to form the air intake and exhaust paths of the entire machine. The first air inlet duct 310 and the first air outlet duct 320 are in soft contact with the inner side of the housing 200. Each air inlet and air outlet duct is a cylindrical structure with an inner diameter that matches the corresponding connection part.

[0063] Understandably, the first air inlet duct 310 and the first air outlet duct 320 at both ends of the fan housing 300 are made of flexible material, and the first air inlet duct 310 and the first air outlet duct 320 are sealed to the second air inlet duct 210 and the second air outlet duct 220. This arrangement ensures soft contact between the fan housing and the box body, thereby reducing vibration, and also reduces wind noise through the sealing arrangement. At the same time, the fact that the inner diameter of the first air inlet duct 310 and the first air outlet duct 320 is the same as the inner diameter of the fan 400 also reduces wind noise. By adding multiple air inlets and outlets, a highly efficient airflow circulation system is constructed, which significantly improves drying efficiency. The first air inlet duct 310 and the first air outlet duct 320 are respectively connected to the two ends of the fan housing 300, forming a dedicated airflow channel for the fan 400: outside air is drawn into the fan housing 300 from the first air inlet duct 310, accelerated by the fan 400, and discharged from the first air outlet duct 320. This process reduces the turbulence loss of airflow inside the housing, maximizing the utilization of the fan's air pressure and air volume. The first air inlet duct 310 and the first air outlet duct 320 are in soft contact with the inner side of the housing 200, effectively preventing the leakage of fan vibration.

[0064] Meanwhile, the second air inlet duct 210 and the second air outlet duct 220 are located on both sides of the box body 200, serving as the main air inlet and outlet channels for the entire machine, forming a dual airflow path of "external-internal-external" with the first air inlet duct 310 and the first air outlet duct 320. The first air inlet duct 310 and the second air inlet duct 210 are sealed together; the first air outlet duct 320 and the second air outlet duct 220 are sealed together, forming a concentrated high-speed airflow that directly acts on the pet's fur, shortening the drying time.

[0065] This design not only improves airflow efficiency but also reduces energy loss by optimizing airflow direction. For example, the shorter air intake path and lower resistance of the fan 400 reduce motor load; while the straightened exhaust path reduces noise from airflow deflection, further enhancing the equipment's quiet operation. Furthermore, the compatible inner diameter and connection points of the multi-cylinder structure prevent air leakage or turbulence caused by dimensional deviations, ensuring stable airflow output and providing reliable support for high-speed drying.

[0066] In some embodiments of this application, it also includes:

[0067] The first fixed bracket 500 is set at the bottom of the inner side of the box body 200;

[0068] The second fixing bracket 510 is set on the top of the box body 200;

[0069] The first fixing groove 330 is formed on the top of the outer side of the fan housing 300;

[0070] The second fixing groove 340 is formed at the bottom of the outer side of the fan housing 300.

[0071] Specifically, the first fixing bracket 500 is a block-shaped structure protruding outward from the bottom of the inner side of the box body 200; the second fixing bracket 510 is a U-shaped structure extending downward from the top of the box body 200; the first fixing groove 330 is a groove recessed inward from the top of the outer side of the fan housing 300, and its shape is adapted to the first fixing strap 520; the second fixing groove 340 is a groove recessed inward from the bottom of the outer side of the fan housing 300, and its shape is adapted to the second fixing strap 530.

[0072] Understandably, by setting the fixing protrusions and fixing grooves, precise installation base points are provided for the fixing straps, significantly enhancing the structural stability of the fan housing 300 within the box body 200. The first fixing bracket 500 is located at the bottom of the inner side of the box body 200, protruding outward in a block or strip shape, and its function is to provide a connection fulcrum for the bottom of the first fixing strap 520; the second fixing bracket 510 is located at the top of the box body 200, resembling a column or strip structure, and is used to fix the top of the second fixing strap 530. These two sets of protrusions are integrally formed with the box body 200, ensuring that they will not shift or deform when bearing the weight of the fan housing 300.

[0073] The first fixing groove 330 and the second fixing groove 340 on the fan housing 300 are respectively adapted to the end shapes of the first fixing strap 520 and the second fixing strap 530. When the fixing strap is connected to the protrusion by means of buckles, bolts, etc., the protrusion structure at the top or bottom can be embedded into the corresponding groove, forming a "point-surface" combination fixing method: on the one hand, the fixing protrusion provides longitudinal tension to the fixing strap to prevent the fan housing 300 from sagging; on the other hand, the fixing groove, through lateral limiting, prevents the fan housing 300 from swaying or rotating from side to side, so that the fan housing 300 remains stable within the box body 200.

[0074] When it is necessary to adjust the installation position of the fan housing 300 or replace a damaged fixing strap, the operation can be completed simply by loosening the connection between the fixing strap and the protrusion or groove, without disassembling other parts. In addition, the precise positioning structure reduces the collision noise caused by installation gaps during fan operation—the fixing groove fits tightly with the end of the fixing strap, eliminating possible wobbling space and further reducing the risk of vibration being transmitted to the housing 200, allowing the equipment to maintain a low noise level even when operating at high speed.

[0075] In some embodiments of this application, the fixing strap includes:

[0076] The first fixing strap 520 is set inside the box body 200. The two ends of the first fixing strap 520 are detachably connected to a first fixing bracket 500 respectively. The top of the first fixing strap 520 is detachably connected to the top of the fan housing 300 through the first fixing groove 330.

[0077] The second fixing strap 530 is located inside the box body 200. The bottom of the second fixing strap 530 is detachably connected to the bottom of the fan housing 300 through the second fixing groove 340. The two ends of the top of the second fixing strap 530 are detachably connected to a second fixing bracket 510 respectively.

[0078] Preferably, the first fixing strap 520 and the second fixing strap 530 are disposed inside the box body 200.

[0079] Specifically, the first fixing strap 520 has a U-shaped structure, with its bottom two ends connected to the first fixing bracket 500 inside the box body 200 through its own buckles, and its top end embedded in the first fixing groove 330 of the fan housing 300 through a structure that matches the first fixing groove 330 to achieve a detachable connection; the second fixing strap 530 has a triangular structure, with its bottom end embedded in the second fixing groove 340 of the fan housing 300 through a structure that matches the second fixing groove 340, and its top two ends connected to the second fixing bracket 510 on the top of the box body 200.

[0080] Understandably, by subdividing the fixing straps into a first fixing strap 520 and a second fixing strap 530, a double-fixing structure is constructed, significantly improving the installation reliability and vibration resistance of the fan housing 300. The first fixing strap 520 is located inside the housing 200, with its bottom ends connected to the first fixing bracket 500 via buckles or bolts, and its top embedded in the first fixing groove 330 on the top of the fan housing 300 via a protruding structure. This "bottom suspension + top support" design subjects the lower half of the fan housing 300 to an upward pulling force, offsetting some of the gravitational force and reducing the stress deformation in the middle of the fixing straps.

[0081] The second fixing strap 530 is embedded in the second fixing groove 340 at the bottom of the fan housing 300, and its top two ends are connected to the second fixing bracket 510 at the top of the box body 200. The upper and lower sets of fixing straps form a symmetrical tension network, which evenly fixes the fan housing 300 in the middle of the box body 200—the second fixing strap 530 at the bottom prevents the fan housing 300 from sagging, and the first fixing strap 520 at the top prevents the fan housing 300 from tilting upwards.

[0082] Traditional single-point fixing straps may break or loosen due to excessive stress at a single point, while double-point fixing straps distribute the weight of the fan housing 300 across the bottom and top of the housing 200, reducing the load on any single fixing point. Simultaneously, the detachable connection between the fixing straps and the fixing protrusions and grooves makes the installation process more flexible—for example, users can adjust the tension of the fixing straps according to the weight of the fan 400, or optimize vibration damping by replacing the fixing straps with different elastic coefficients. For the high-speed operating fan 400, a stable installation structure reduces additional noise caused by shaking, while preventing component loosening due to vibration (such as the loosening of the connecting screws between the fan 400 and the fan housing 300), improving the long-term reliability of the equipment. Furthermore, the double-point fixing strap design also provides cushioning protection in the event of an accidental drop, reducing the risk of damage from a collision between the fan housing 300 and the housing 200.

[0083] In some embodiments of this application, it also includes:

[0084] Ventilation and sound insulation device 700, two ventilation and sound insulation devices 700 are detachably connected to the second air inlet duct 210 and the second air outlet duct 220 respectively.

[0085] Specifically, the ventilation soundproof device 700 consists of two independent cylindrical structures, which are installed at the ports of the second air inlet duct 210 and the second air outlet duct 220 respectively by means of snap-fit, thread, etc. The interior is filled with soundproof material or has a soundproof structure to block the noise of the fan from escaping while maintaining unobstructed airflow.

[0086] Understandably, by installing ventilation soundproof devices 700 at the second air inlet duct 210 and the second air outlet duct 220, a double noise reduction barrier is constructed, further enhancing the equipment's quietness performance. The ventilation soundproof device 700 is an independent block or cover-shaped structure, filled with sound-insulating materials (such as sound-absorbing cotton or foam plastic) or equipped with sound-insulating structures (such as labyrinthine channels or resonant cavities). It is installed at the air inlet and outlet duct ports in a detachable manner using snaps, threads, etc., blocking the noise leakage of the fan while maintaining unobstructed airflow.

[0087] By employing a dual approach—a fixed, suspended installation to reduce vibration noise and a 700-unit ventilation soundproof unit to block fan noise leakage—the overall noise level can be reduced to 50-60 decibels, approaching the level of everyday conversation, significantly improving the pet grooming experience. Furthermore, the removable 700 ventilation soundproof unit facilitates regular cleaning—pet hair can adhere to the surface of the soundproofing material with airflow, affecting noise reduction. The easy-to-remove design allows users to remove the 700, clean the hair, and reinstall it, maintaining long-term noise reduction performance. For commercial settings such as pet grooming salons, this low-noise equipment can also create a quieter working environment, improving customer satisfaction while reducing noise pollution for staff.

[0088] In some embodiments of this application, it also includes:

[0089] The snap-fit ​​protrusion 610 is located inside the fan housing 300 at one end near the air outlet;

[0090] A snap-fit ​​groove 620 is formed on the surface of the snap-fit ​​protrusion 610;

[0091] The snap-fit ​​tab 630 is detachably connected to the snap-fit ​​protrusion 610 via the snap-fit ​​groove 620.

[0092] Heating wire 600 is disposed on the surface of snap-fit ​​piece 630.

[0093] Specifically, the snap-fit ​​protrusion 610 is a block-shaped or columnar structure protruding inward from the end of the fan housing 300 near the first air outlet 320, and the snap-fit ​​groove 620 opened on its surface is an annular groove, a strip groove or other suitable groove, used to cooperate with the snap-fit ​​piece 630.

[0094] Specifically, the snap-fit ​​piece 630 has a sheet-like structure, and two snap-fit ​​pieces 630 are snapped together to form a cross structure. The edge of the snap-fit ​​piece 630 is provided with a protrusion or buckle to fix the heating wire. The snap-fit ​​piece 630 is detachably connected to the snap-fit ​​protrusion 610 by embedding into the snap-fit ​​groove 620. The heating wire 600 is evenly distributed or wound on the surface of the snap-fit ​​piece 630, and can heat the airflow after being energized.

[0095] Understandably, by setting the snap-fit ​​protrusion 610 and snap-fit ​​groove 620 inside the fan housing 300, a convenient component installation interface is constructed, laying the foundation for the subsequent integration of heating components. The snap-fit ​​protrusion 610 is located inside the fan housing 300 near the end of the first air outlet duct 320, protruding inward in a block or column shape, and the snap-fit ​​groove 620 on its surface can be an annular groove, a strip groove, or other adaptable shapes. The core advantage of this structural design is that it enables tool-free rapid installation: when it is necessary to install the snap-fit ​​piece 630, simply align the edge protrusion of the snap-fit ​​piece 630 with the snap-fit ​​groove 620 and press gently to fix it through the snap-fit ​​structure; when disassembling, apply force in the opposite direction to remove the snap-fit ​​piece 630, greatly shortening maintenance time.

[0096] The reliable snap-fit ​​structure ensures that the heating wire 600 will not fall off due to vibration when the fan is running at high speed. The snap-fit ​​groove 620 and the protrusion of the snap-fit ​​piece 630 engage tightly to form a mechanical lock, avoiding the loosening problems that may occur due to vibration caused by traditional screw fixing. Secondly, the detachable design makes it easy for users to regularly clean the hair or dust accumulation near the snap-fit ​​protrusion 610. Pet hair may enter the fan housing 300 with the airflow during the drying process. If it accumulates around the snap-fit ​​structure, it may affect the installation accuracy of the snap-fit ​​piece 630 or cause poor heat dissipation of the heating wire 600. The convenient disassembly function allows users to easily clean the hard-to-reach areas and maintain equipment performance. In addition, the position of the snap-fit ​​protrusion 610 is close to the air outlet, so that the heating component is as close as possible to the airflow outlet, reducing the residence time of heated air inside the housing, reducing heat loss, ensuring stable hot air temperature, and improving drying efficiency.

[0097] Understandably, the combination of the snap-fit ​​tab 630 and the heating wire 600 enables flexible integration and efficient operation of the hot air function. The snap-fit ​​tab 630, serving as the carrier of the heating wire 600, is detachably connected to the snap-fit ​​groove 620 via protrusions on its edge. This design makes the heating component an independent module—when the heating wire 600 malfunctions (such as open circuit or overheat protection), the user does not need to disassemble the entire fan housing 300; they can simply remove the snap-fit ​​tab 630 for individual replacement, significantly reducing maintenance complexity and cost. Simultaneously, the sheet-like structure of the snap-fit ​​tab 630 can evenly distribute the heating wire 600. For example, the heating wire 600 can be wound into a spiral or laid flat on the surface of the snap-fit ​​tab 630, ensuring that the airflow makes full contact with the heating wire 600, absorbing heat and avoiding localized overheating or uneven heating.

[0098] The heating wire 600 heats up rapidly after being powered on, heating the high-speed airflow output by the fan 400 to a suitable temperature (e.g., 38-42℃), meeting the need for quick hair drying while preventing burns to the pet's skin. The detachable design of the clip 630 allows users to adjust the heating element according to the season or pet's coat type—for example, the clip 630 can be removed in summer for cool air mode, while it can be installed in winter for hot air mode, improving the device's versatility. Furthermore, the surface-fitting design of the heating wire 600 and clip 630 reduces airflow resistance—the smooth surface of the clip 630 prevents turbulence caused by the heating wire 600 being directly exposed to the airflow, reducing noise and improving airflow stability, ensuring even hot air distribution and shortening the pet's hair drying time.

[0099] In some embodiments of this application, it also includes:

[0100] The heat dissipation base 800 is located at the bottom of the box body 200;

[0101] Heat sink 900, several heat sinks 900 are set on the bottom surface of heat sink base 800.

[0102] Preferably, the heat dissipation base 800 is arranged horizontally at the bottom of the box body 200; a plurality of heat dissipation fins 900 are arranged vertically on the bottom surface of the heat dissipation base 800.

[0103] Specifically, the heat dissipation base 800 is a plate-shaped structure fixed to the bottom of the box body 200. Several heat dissipation fins 900 are distributed on its bottom surface. The heat dissipation fins 900 are long strips or sheet-like structures to increase the heat dissipation area and improve heat dissipation efficiency.

[0104] Understandably, the combination of the heat dissipation base 800 and the heat sink 900 constructs a highly efficient heat dissipation system, ensuring the safety and stability of the equipment during long-term operation. The heat dissipation base 800 is a plate-like structure fixed to the bottom of the housing 200. Its material is a metal with excellent thermal conductivity (such as aluminum alloy), which can quickly absorb the heat generated inside the equipment (such as the fan 400 and heating wire 600). The several heat sinks 900 on the bottom surface are elongated or sheet-like, significantly improving heat dissipation efficiency by increasing the surface area—according to the principle of heat conduction, the larger the surface area of ​​the heat sink 900, the larger the contact area with the air, and the faster the heat is dissipated through air convection.

[0105] During operation, both the motor of the blower 400 and the heating wire 600 generate a significant amount of heat. If this heat cannot be dissipated in time, it may cause the motor to overheat and shut down, shorten the lifespan of the heating wire 600, or even pose a safety hazard. The design of the heat dissipation base 800 and heat sink 900 effectively reduces the internal temperature: for example, when the heating wire 600 heats the airflow, some of the heat is conducted to the blower housing 300 through the snap-fit ​​tab 630, then transferred to the housing 200 via the fixing strap, and finally dissipated to the external environment by the heat dissipation base 800 and heat sink 900. Cool air from the top enters from the side of the housing 200, absorbs heat as it flows through the heat sink 900, and the hot air is exhausted from the bottom, forming a continuous cooling cycle.

[0106] Furthermore, the design of the heat sink 900 facilitates user cleaning: the gaps between its fins allow for easy dust removal using a soft brush or compressed air, preventing dust accumulation on the surface of the heat sink 900 and ensuring effective heat dissipation. For the high-frequency use of pet grooming, efficient heat dissipation means the device can operate continuously for longer periods without frequent shutdowns for cooling, improving grooming efficiency. Simultaneously, stable temperature control protects the motors of the heating element 600 and the fan 400, extending the overall lifespan of the device and reducing long-term operating costs.
