Description

Technical Field

[0001] This utility model relates to the field of air foot bath technology, specifically a V-shaped hot air guide plate for an air foot bath. Background Technology

[0002] In the field of health and wellness appliances, air foot baths, as devices that can provide comfortable heating care for the feet through hot air circulation, promote blood circulation, and relieve fatigue, have become increasingly popular among consumers. Among them, the hot air guide plate is one of the key components for air foot baths to achieve efficient hot air circulation and uniform heating.

[0003] A hot air deflector is a special structural deflector designed to optimize the flow path of hot air and improve the heating effect. Its core design concept is to guide and distribute the hot air entering the foot bath tub using a specific shape and layout. Existing hot air deflectors suffer from uneven hot air distribution and low thermal efficiency. Some hot air deflectors cannot effectively and evenly diffuse hot air to the entire foot placement area, and the hot air often concentrates in certain local areas, resulting in large differences in heating different parts of the foot. Some areas are too hot and may burn the user's feet, while some areas are too cold and cannot achieve the ideal heating and care effect, which seriously affects the user experience. The heat exchange between the hot air and the surrounding environment is not sufficient during the flow process, and there is a lot of heat loss. Therefore, it is necessary to design a V-shaped hot air deflector for the foot bath tub to improve the above problems. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a V-shaped hot air guide plate for an air foot bath bucket, which interferes with the airflow path, generates a controllable vortex, accelerates the mixing of hot air with the surrounding cold air, prolongs the residence time of hot air in the action area, improves heat conduction efficiency, and achieves a uniform temperature distribution effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A V-shaped hot air guide plate for an air foot bath includes a hot air heat-conducting plate body, which is installed at the bottom of a foot placement plate inside the air foot bath body. The hot air heat-conducting plate body has a ventilation opening, and a baffle plate is provided above the ventilation opening. The center of the baffle plate is recessed inward to form a guide area, which is conical in shape. Support blocks are fixedly connected to the baffle plate and the hot air heat-conducting plate body around its perimeter.

[0006] Preferably, the projection of the baffle plate onto the hot air heat-conducting plate body covers the vent.

[0007] Preferably, the hot air heat-conducting plate body has an outer perimeter plate surrounding the top perimeter.

[0008] Preferably, the height of the top surface of the wind deflector is lower than the height of the top surface of the outer perimeter plate.

[0009] Preferably, right-angle connecting plates are fixedly connected to the outer walls of the perimeter plate.

[0010] Preferably, a sealing groove is formed at the top of the outer plate, and a sealing ring is embedded in the sealing groove, the sealing ring protruding from the top surface of the outer plate.

[0011] Preferably, a mounting bracket is fixedly connected to the bottom of the hot air heat conduction plate body and outside the vent.

[0012] Preferably, the mounting bracket, outer plate, support block, wind baffle, and hot air heat conduction plate body are integrally injection molded.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a hot air heat-conducting plate body, a baffle plate, and a guide zone. Hot air is delivered from bottom to top into the hot air receiving cavity through the ventilation opening. The guide zone of the baffle plate optimizes the flow state of the hot air. After the high-speed hot air impacts the cone-shaped guide zone, it is forced to spread out evenly radially along the cone surface. This guide method disrupts the laminar flow of the hot air, enhances turbulence, interferes with the airflow path, generates controllable vortices, and accelerates the mixing of hot air with the surrounding cold air. At the same time, the airflow speed decreases after impacting the cone-shaped guide zone, prolonging the residence time of the hot air in the action area, improving heat conduction efficiency, and making the temperature distribution uniform. This ensures that the feet are not scalded when exposed to the hot air, and provides better bottom contact, effectively caring for the feet and promoting blood circulation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figures 1-3 This embodiment provides a V-shaped hot air guide plate for an air bath foot tub, including a hot air heat-conducting plate body 1. The hot air heat-conducting plate body 1 is installed at the bottom of the foot placement plate inside the air bath foot tub body 2. The air bath foot tub body 2 is prior art and will not be described in detail here. A ventilation opening 102 is provided on the hot air heat-conducting plate body 1, and a baffle plate 103 is provided above the ventilation opening 102. The center of the baffle plate 103 is recessed inward to form a guide area 104. Support blocks 105 are fixedly connected to the baffle plate 103 and the hot air heat-conducting plate body 1 around the perimeter of the baffle plate 103. One end of the support block 105 is fixedly connected to the baffle plate 103, and the other end of the support block 105 is fixedly connected to the baffle plate 103. One end is fixedly connected to the hot air heat conduction plate body 1. The top of the hot air heat conduction plate body 1 is provided with an outer peripheral plate 101 around it. The space between the outer peripheral plate 101 and the top of the hot air heat conduction plate body 1 forms a hot air receiving cavity. Hot air is delivered from bottom to top into the hot air receiving cavity through the vent 102. The flow state of the hot air is optimized by the guide area 104 of the baffle plate 103, thereby improving thermal efficiency, improving temperature uniformity and reducing energy consumption. This makes the hot air evenly distributed on the bottom of the foot placement plate, and the temperature is evenly distributed, so that the feet do not get burned when they come into contact with the hot air. The bottom contact provides better and more effective care for the human feet and promotes blood circulation.

[0018] In this embodiment, the projection of the baffle plate 103 on the hot air heat-conducting plate body 1 covers the vent 102, so that the length and width of the baffle plate 103 are both greater than the length and width of the vent 102. The baffle plate 103 can cover the vent 102. The hot air passing through the vent 102 needs to be guided by the baffle plate 103. The guide area 104 is conical in shape, and the longitudinal section of the guide area 104 is a V-shaped structure. The high-speed hot air coming from the front is forced to diffuse outward through the guide area 104. The principle is similar to the "collision effect". After the high-speed airflow hits the cone, the kinetic energy is converted into pressure energy, which forces the airflow to spread outward evenly along the cone surface, destroying laminar flow, enhancing turbulence, interfering with the airflow path, generating controllable vortices, and accelerating the mixing of hot air with the surrounding cold air. After the airflow hits the cone of the guide area 104, the speed decreases, prolonging the residence time of the hot air in the action area and improving the heat transfer efficiency.

[0019] In this embodiment, a sealing groove is formed at the top of the outer plate 101, and a sealing ring 107 is embedded in the sealing groove. The sealing ring 107 protrudes from the top surface of the outer plate 101. Right-angle connecting plates 106 are fixedly connected to the outer walls of the outer plate 101. One end of the right-angle connecting plate 106 is connected and fixed to the outer plate 101 by bolts, and the other end of the right-angle connecting plate 106 has a mounting hole. A mounting groove is formed at the bottom of the foot placement plate inside the air bubble foot barrel body 2, and the position of the mounting groove corresponds to the position of the outer plate 101. When assembling the hot air heat-conducting plate body 1 with the foot placement plate, the top of the outer plate 101 of the hot air heat-conducting plate body 1 is aligned and inserted into the mounting groove of the foot placement plate. Then, bolts are passed through the mounting holes and connected and fixed to the foot placement plate to complete the installation of the hot air heat-conducting plate body 1 and the foot placement plate. The sealing ring 107 is pressed against the mounting groove to seal the gap between the outer plate 101 and the foot placement plate, improve the sealing performance, prevent hot air from escaping from the hot air receiving cavity, and effectively utilize the hot air for foot heating and care.

[0020] In this embodiment, the height of the top surface of the baffle plate 103 is lower than the height of the top surface of the outer plate 101. Through this structural design, the baffle plate 103 is placed in the hot air receiving cavity, avoiding obstruction to the installation of the hot air heat-conducting plate body 1.

[0021] In this embodiment, a mounting bracket 108 is fixedly connected to the bottom of the hot air heat conduction plate body 1 and outside the vent 102. The mounting bracket 108 is used to install and assemble the heating module and the fan. The fan blows air into the heating module, and the heating module heats the air into hot air and delivers it into the hot air receiving cavity to achieve the heating of the feet.

[0022] In this embodiment, the mounting bracket 108, the outer plate 101, the support block 105, the wind baffle 103 and the hot air heat conduction plate body 1 are integrally injection molded, which enhances the integrity and rigidity of the hot air heat conduction plate body 1 structure, improves the deformation resistance, impact resistance and vibration resistance of the hot air heat conduction plate body 1, and makes it more durable and reliable.

[0023] Working principle: When assembling the hot air heat conduction plate body 1 with the foot placement plate, the top of the outer plate 101 of the hot air heat conduction plate body 1 is aligned and inserted into the mounting groove of the foot placement plate. Then, the hot air heat conduction plate body 1 and the foot placement plate are connected and fixed with bolts through the mounting holes on the right-angle connecting plate 106. The sealing ring 107, which is embedded in the sealing groove at the top of the outer plate 101, protrudes from the top surface of the outer plate 101 and will press against the mounting groove after installation, sealing the gap between the outer plate 101 and the foot placement plate. To prevent hot air from escaping from the hot air receiving cavity and ensure that the hot air is effectively used for foot heating care, the fan installed on the mounting bracket 108 on the outside of the bottom vent 102 of the hot air heat conduction plate body 1 starts to work, drawing in air from the outside. At the same time, the heating module on the mounting bracket 108 also starts to work, heating the air drawn in by the fan into hot air. The heated hot air is then delivered from bottom to top through the vent 102 into the hot air receiving cavity formed by the space between the outer plate 101 and the top of the hot air heat conduction plate body 1. Because the projection of the baffle plate 103 on the hot air heat-conducting plate body 1 covers the vent 102, the hot air passing through the vent 102 will encounter the baffle plate 103. After the high-speed hot air hits the cone-shaped guide area 104 formed by the inward indentation at the center of the baffle plate 103, a "collision effect" is generated, and the kinetic energy is converted into pressure energy, forcing the hot air to spread out evenly and radially along the cone surface. This guide method disrupts the laminar flow state of the hot air, enhances the turbulence, interferes with the airflow path, generates controllable vortices, and accelerates the mixing of hot air with the surrounding cold air. At the same time, the airflow speed decreases after hitting the cone of the guide area 104, prolongs the residence time of the hot air in the action area, improves the heat conduction efficiency, makes the temperature evenly distributed, and ensures that the feet are not scalded when in contact with the hot air. The bottom contact provides better and more effective care for the human feet and promotes blood circulation.

[0024] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
