Description

Technical Field

[0001] This invention relates to the field of air purification, and more particularly to a bathroom sterilization and deodorization device. Background Technology

[0002] Bathrooms are characterized by high humidity and strong odors. Paper-based filters and associated air purifiers have short lifespans and are prone to odor residue. Therefore, methods such as ultraviolet (UV) irradiation and photocatalysis are used in bathrooms for sterilization and deodorization. However, considering the high frequency of use and high turnover of people in bathrooms, UV irradiation, due to its unique physical and chemical properties, can only be used for specific time periods. Photocatalysis, on the other hand, does not produce toxic substances and is harmless to the human body, making it more advantageous than UV irradiation.

[0003] The aforementioned paper-based filter cartridges and their associated air purification equipment have short service lifespans and are prone to odor residue. Therefore, removing the paper filter cartridge is necessary. However, this leads to the problem that, without the paper filter cartridge as a barrier, the exposed photocatalytic mesh, combined with the high humidity of the environment, will adhere to airborne particles, causing mesh blockage, particle deposition, and odor problems. Therefore, this invention proposes a bathroom sterilization and deodorization device with the exposed photocatalytic mesh as its main technical feature, which can reduce particle deposition and odor dispersion. Summary of the Invention

[0004] The purpose of this invention is to provide a bathroom sterilization and deodorization device to solve the technical problem that after the paper filter is removed, the exposed photocatalytic mesh will adhere to airborne particles due to the high humidity of the environment, causing mesh blockage and odor from particle deposition.

[0016] Preferably, a transition sleeve with multiple linkage rod movable slots is provided at the first main shaft, wherein one linkage rod is transferred into each linkage rod movable slot;

[0017] And a support block, which is located at the bottom of the movable groove of the linkage rod, and the support block and the linkage rod are supported by a spring. After the lamp post presses the linkage rod downward, the linkage rod touches the inside of the photocatalyst mesh cover, so that the photocatalyst mesh cover is rigidly connected to the first main shaft.

[0018] Preferably, a plurality of limiting grooves parallel to the axis of the lamp post are arranged around the outer wall of the lamp post, wherein the limiting groove has a locking block that extends into the limiting groove or retracts into the lamp post from the limiting groove;

[0019] And a buckle, which is set at the edge of the opening where the lamp post extends into the photocatalyst mesh cover, wherein the buckle extends into the limiting groove to contact the locking block, or to contact the end of the limiting groove.

[0020] Preferably, when the latch contacts the latch block, the lamp post moves away from and does not contact the linkage rod.

[0021] Preferably, when the buckle contacts the end of the limiting groove, the lamp post presses down the linkage rod and causes the linkage rod to touch the inside of the photocatalyst mesh cover.

[0022] Preferably, a lamp rod is installed inside the lamp post, and the lamp post is made of a light-transmitting material, so that the light emitted by the lamp rod can penetrate the lamp post and illuminate the photocatalyst mesh cover.

[0033] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0034] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0035] Example 1

[0036] This embodiment presents a toilet sterilization and deodorization device; please refer to [link / reference]. Figure 1 The main body of the bathroom sterilization and deodorization device consists of a support member with a suction section and a photocatalytic component installed above the support member.

[0037] Specifically, support components with suction sections, such as Figure 2-4 As shown, it includes a base 1 and a motor 14 disposed within the base 1.

[0038] The base 1 has a cavity for mounting the motor 14 and for airflow. In addition, the outer wall of the base 1 has a series of air ducts 6 arranged in a ring to connect the cavity where the motor 14 is located with the space outside the base 1. Furthermore, a counterweight 20 is added to the base 1 to lower the center of gravity of the entire device and prevent it from tipping over.

[0039] The motor 14 has a first main shaft 10 and a second main shaft 16, wherein the first main shaft 10 and the second main shaft 16 are respectively disposed at two ends of the motor 14. The first main shaft 10 extends into the photocatalyst mesh cover 2 and is directly opposite the lamp post 4. The second main shaft 16 is placed in the accommodating cavity and is adjacent to the air duct 6. Thus, the blade assembly 15 is fixed at the second main shaft 16 and promotes airflow when the second main shaft 16 rotates axially.

[0040] Photocatalytic components, such as Figure 7 As shown, it includes the main structure such as the protective cover 5, the photocatalytic mesh cover 2, and the lamp post 4.

[0041] The shield 5 is located above the support member, and the outer periphery of the shield 5 has three openings 3 arranged as air inlets for the support member.

[0042] For the photocatalyst mesh cover 2, the photocatalyst mesh cover 2 is placed inside the protective cover 5 and moves in close contact with the protective cover 5.

[0043] The lamp post 4 has a lamp rod 21 installed inside it, and the lamp post 4 is made of a light-transmitting material so that the light emitted by the lamp rod 21 can penetrate the lamp post 4 and illuminate the photocatalyst mesh cover 2. To further explain, the lamp post 4 is inserted into the photocatalyst mesh cover 2 by the axis of the protective cover 5 and is limited to the axial rotation of the photocatalyst mesh cover 2 within the protective cover 5. The protective cover 5 has an opening that is always exposed at the opening 3. In addition, several flexible rods are attached to the side of the protective cover 5 that contacts the photocatalyst mesh cover 2. When the photocatalyst mesh cover 2 rotates axially within the protective cover 5, the flexible rods push against the opening outside the opening 3.

[0044] In this embodiment, for cleaning the photocatalyst mesh cover 2, an external force is applied to the surface of the photocatalyst mesh cover 2 exposed at the opening 3, causing the photocatalyst mesh cover 2 to rotate axially within the protective cover 5. Then, the flexible rod pushes into the opening outside the opening 3 to peel off the particles deposited in the opening. In addition, for particles attached to the surface of the photocatalyst mesh cover 2, the surface of the photocatalyst mesh cover 2 can be cleaned by rubbing the edge of the opening 3 during the axial rotation of the photocatalyst mesh cover 2 relative to the protective cover 5.

[0045] Example 2

[0046] This embodiment presents a toilet sterilization and deodorization device; please refer to [link / reference]. Figure 1 The main body of the bathroom sterilization and deodorization device consists of a support member with a suction section and a photocatalytic component installed above the support member.

[0047] Specifically, support components with suction sections, such as Figure 2-4 As shown, it includes a base 1 and a motor 14 disposed within the base 1.

[0048] The base 1 has a cavity for mounting the motor 14 and for airflow. In addition, the outer wall of the base 1 has a series of air ducts 6 arranged in a ring to connect the cavity where the motor 14 is located with the space outside the base 1. Furthermore, a counterweight 20 is added to the base 1 to lower the center of gravity of the entire device and prevent it from tipping over.

[0049] The motor 14 has a first main shaft 10 and a second main shaft 16, wherein the first main shaft 10 and the second main shaft 16 are respectively disposed at two ends of the motor 14. The first main shaft 10 extends into the photocatalyst mesh cover 2 and is directly opposite the lamp post 4. The second main shaft 16 is placed in the accommodating cavity and is adjacent to the air duct 6. Thus, the blade assembly 15 is fixed at the second main shaft 16 and promotes airflow when the second main shaft 16 rotates axially.

[0050] Photocatalytic components, such as Figure 7 As shown, it includes the main structure such as the protective cover 5, the photocatalytic mesh cover 2, and the lamp post 4.

[0051] The shield 5 is located above the support member, and the outer periphery of the shield 5 has three openings 3 arranged as air inlets for the support member.

[0052] For the photocatalyst mesh cover 2, the photocatalyst mesh cover 2 is placed inside the protective cover 5 and moves in close contact with the protective cover 5.

[0053] The lamp post 4 has a lamp rod 21 installed inside it, and the lamp post 4 is made of a light-transmitting material so that the light emitted by the lamp rod 21 can penetrate the lamp post 4 and illuminate the photocatalyst mesh cover 2. To further explain, the lamp post 4 is inserted into the photocatalyst mesh cover 2 by the axis of the protective cover 5 and is limited to the axial rotation of the photocatalyst mesh cover 2 within the protective cover 5. The protective cover 5 has an opening that is always exposed at the opening 3. In addition, several flexible rods are attached to the side of the protective cover 5 that contacts the photocatalyst mesh cover 2. When the photocatalyst mesh cover 2 rotates axially within the protective cover 5, the flexible rods push against the opening outside the opening 3.

[0054] Unlike Embodiment 1, in this embodiment, cleaning the photocatalyst mesh cover 2 involves applying force to the inside of the photocatalyst mesh cover 2, causing the photocatalyst mesh cover 2 to rotate axially within the protective cover 5.

[0055] For details, please refer to Figure 4-6 An adapter sleeve 11 with multiple linkage rod movable slots 9 is provided at the first main shaft 10. Each linkage rod movable slot 9 is connected to a linkage rod 8. In addition, there is a support block 13, which is located at the bottom of the linkage rod movable slot 9. The support block 13 and the linkage rod 8 are supported by a spring 12. After the lamp post 4 presses the linkage rod 8 downward, the linkage rod 8 touches the inside of the photocatalyst mesh cover 2, so that the photocatalyst mesh cover 2 is rigidly connected to the first main shaft 10.

[0056] The following, combined with Figure 5 and Figure 6 The content shown explains the principle of how force is applied to the inside of the photocatalyst mesh cover 2, causing the photocatalyst mesh cover 2 to rotate axially within the protective cover 5:

[0057] ①For example Figure 5 As shown, when the lamp post 4 moves away from the linkage rod 8, the spring 12 supports the linkage rod 8 to rotate upwards away from the photocatalyst mesh cover 2. In addition, even if the first main shaft 10 rotates axially and centrifugal force is applied to the linkage rod 8, the linkage rod 8 will at most be perpendicular to the first main shaft 10 and will not contact the photocatalyst mesh cover 2. In this state, as can be referred to in Embodiment 1, only when an external force is applied to the surface of the photocatalyst mesh cover 2 exposed at the opening 3 can the photocatalyst mesh cover 2 be rotated axially within the protective cover 5.

[0058] ② After the lamp post 4 presses down on the linkage rod 8 (the groove 19 corresponding to the linkage rod 8 at the lamp post 4 presses down on the linkage rod 8), the linkage rod 8 rotates down until it contacts the photocatalyst mesh cover 2, so that the photocatalyst mesh cover 2 is rigidly connected to the first main shaft 10. When rigidly connected, when the first main shaft 10 rotates axially, the photocatalyst mesh cover 2 is linked with the first main shaft 10, so that the soft rod top is located in the opening outside the opening 3, and the particles deposited in the opening are peeled off.

[0059] As explained in ① and ②, lamp post 4 is a control component. For more information on lamp post 4, please refer to [link / reference needed]. Figure 4The outer wall of the lamp post has three limiting grooves 17 parallel to the axis of the lamp post 4. Each limiting groove 17 has a locking block 18 that extends into the lamp post 4 or retracts into the lamp post 4. Additionally, the lamp post 4 has a buckle corresponding to each of the three limiting grooves 17 at the edge of the opening where it enters the photocatalyst mesh cover 2. The buckle either extends into the limiting groove 17 to contact the locking block 18 or contacts the end of the limiting groove 17.

[0060] To further explain, such as Figure 5 As shown, when the latch contacts the latch block 18, the lamp post 4 moves away from and does not contact the linkage rod 8, which corresponds to ① above.

[0061] like Figure 6 As shown, when the latch contacts the end of the limiting groove 17, the lamp post 4 presses down the linkage rod 8 and makes the linkage rod 8 touch the inside of the photocatalyst mesh cover 2, which corresponds to ② above.

[0062] In Embodiments 1 and 2, the fixing component of the motor 14 in the base 1 is a heat sink 7. Specifically, multiple heat sinks 7 are arranged around the motor 14, and the other end of the heat sink 7 is fixed to the inner wall of the base 1, thereby placing the motor 14 at the center line of the accommodating cavity.

[0063] To further explain, such as Figure 4 As shown, the space between adjacent heat dissipation plates 7 is an airflow channel. With this arrangement, for bathrooms with high humidity, on the one hand, some heat is filled into the entire device, avoiding the odor problem caused by moisture lingering in the device (and also preventing moisture from entering the device and causing corrosion). On the other hand, as the blade assembly 15 rotates, the heat carried away is guided by the air duct 6 and blows directly to the ground in a 360° omnidirectional manner, thereby addressing the odor problem at its source.

[0064] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
