Description

Technical Field

[0001] The invention belongs to the technical field of protective mesh covers, and in particular relates to a protective mesh cover and a portable electric volatilization device. Background Art

[0002] In a liquid volatilization device, liquids are converted into gaseous media due to their volatilization characteristics. When these gases enter the volatilization area of ​​the device, they exchange heat with the ambient temperature or cooling surface, gradually cool down and condense, and then turn into liquid substances. Condensed droplets may adhere to the surface of the structure such as the protective mesh, causing a series of potential problems.

[0003] As condensation droplets accumulate, a liquid film or droplet accumulation may appear on the surface of the protective mesh. The accumulation of condensed liquid will hinder the normal function of the mesh, especially in application scenarios that require high permeability. If there are too many condensation droplets, on the one hand, it will make the surface of the protective mesh greasy, and on the other hand, it will affect the mesh's airflow guidance ability, reduce the efficiency of gas passing through the mesh, and even cause gas flow obstruction or turbulence. Summary of the invention

[0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a protective mesh cover and a portable electric volatilization device.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] Provided is a protective mesh cover having a volatilization cavity formed by a mesh surface, which is used for liquid high-temperature volatilization equipment, and the mesh opening rate of the volatilization area is not less than 60%;

[0008] The mesh edges of not less than 30% of the volatilization area have cone angles pointing in roughly the same direction.

[0009] Preferably, the cone angle is 20-80°.

[0010] Preferably, the cone angle is 30-50°.

[0011] Preferably, the mesh with a cone angle is a diamond mesh.

[0012] Preferably, the mesh opening rate of the volatilization area is 70-95%.

[0013] Preferably, it has:

[0014] Liquid storage area;

[0015] The liquid storage area is a solid surface structure, suitable for storing small droplets.

[0016] Preferably, it has:

[0017] A thin-wall bridge is arranged in the volatilization area;

[0018] Wherein, the thin-wall bridge passes through a plurality of meshes located in the same column or row.

[0019] Preferably, there are multiple thin-wall bridges, which are arranged parallel to each other.

[0020] Preferably, the protective mesh includes a connection area;

[0021] The connection area has a positioning groove.

[0022] Preferably, the connecting area has an elastic snap-fit ​​structure.

[0023] The present invention also provides a portable electric volatilization device, comprising:

[0024] an electric heating element configured to be connected to a power supply element to provide heat energy;

[0028] Preferably, it includes:

[0029] Equipment housing;

[0030] The device housing comprises a first housing and a second housing which are separable and dockable;

[0032] The volatile area of ​​the protective mesh cover is exposed to the external environment when the first shell and the second shell are separated.

[0033] The present invention provides a protective mesh cover, and the beneficial effects of the present invention are embodied in:

[0034] On the one hand, by designing the mesh opening rate of the protective mesh cover to be not less than 60%, the permeability of the gas can be effectively improved, ensuring that the volatile gas can pass through the mesh cover smoothly. This helps to reduce the resistance of gas flow and enable the volatile substances to diffuse quickly and evenly to the external environment. The mesh 102 with a high opening rate provides a larger space for the condensed medium droplets, thereby reducing the accumulation of droplets on the surface of the mesh cover.

[0035] On the other hand, the mesh edge has a certain cone angle (usually pointing roughly in the same direction) to solve the problem of droplet accumulation on the mesh surface after condensation. The design of the cone angle allows the droplet to effectively guide the flow of the droplet through the inclined structure of the edge when it hits the edge of the mesh. Due to the existence of the cone angle, the droplet will not directly adhere to the edge of the mesh after condensation, but will be guided in a certain direction, reducing the contact area between the droplet and the mesh surface, thereby reducing droplet adhesion.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 9 As shown, the specific embodiments provided by the present invention are as follows:

[0049] refer to Figure 1 As shown, the protective mesh cover 1 includes a first surface and a second surface. The first surface is an inner wall surface, and the second surface is an outer wall surface. The first surface encloses a volatilization cavity, which is used to physically isolate the heating element and the volatilization element of the liquid volatilization device. The second surface is an end surface facing the external environment.

[0050] The protective mesh cover 1 has a volatilization area 101 located on the circumferential wall of the mesh cover. Specifically, the volatilization area 101 includes part or all of the circumferential wall of the volatilization chamber. When the protective mesh cover 1 is applied to a product, the volatilized gas formed by the volatilized liquid will diffuse from the volatilization chamber to the external environment. The circumferential wall of the volatilization area 101 is provided with mesh holes 102 to form a mesh structure to achieve diffusion and isolation of the volatilized gas.

[0051] It should be understood that the volatilization chamber is formed through a plurality of mesh holes 102 penetrating the circumferential wall of the protective mesh cover 1 to form a mesh enclosure structure to ensure the diffusion and flow of the volatile gas in the mesh cover.

[0052] refer to Fig. 9 As shown, the opening ratio of the mesh 102 in the volatilization area 101 is not less than 60%. The opening ratio refers to the ratio of the opening area S2 of a single mesh 102 to the overall area S1 of the mesh 102 (including the connection area around the hole), usually expressed as a percentage. Specifically, the higher the opening ratio of the mesh 102, the larger the area ratio of the mesh 102, thereby increasing the permeability and volatilization efficiency of the gas.

[0053] On the other hand, at least 30% of the area of ​​the volatilization region 101 has a taper angle 103 pointing in the same direction. The taper angle 103 refers to the angle between the two edges of the mesh 102, and the angle is an acute angle, that is, the edge of the mesh 102 has a certain degree of sharpness.

[0054] The purpose of this structural setting is, on the one hand, by designing the mesh 102 of the protective mesh cover 1 to have an opening rate of not less than 60%, the permeability of the gas can be effectively improved to ensure that volatile gases can pass through the mesh cover smoothly. This helps to reduce the resistance to gas flow, allowing volatile substances to quickly and evenly diffuse into the external environment. The mesh 102 with a high opening rate allows more gas to pass through, thereby reducing the probability of condensation droplets forming on the surface of the mesh cover. This is because the larger mesh 102 openings allow the airflow to flow more smoothly, reducing the time that the gas stays near the mesh 102, thereby reducing the chance of gas cooling and condensation, and reducing the probability of droplet adhesion. Therefore, the optimized mesh 102 opening rate not only improves gas fluidity, but also plays an effective role in guiding the flow and reduces the adhesion of condensation droplets to the mesh cover;

[0055] On the other hand, the edge of the mesh 102 has a certain cone angle 103 (usually pointing in roughly the same direction) in order to solve the problem of accumulation of droplets on the surface of the mesh cover after condensation. The design of the cone angle 103 allows the droplets to be effectively guided to flow through the cone angle 103 when they hit the edge of the mesh 102. Due to the existence of the cone angle 103, the droplets will not directly adhere to the edge of the mesh 102 after condensation, but will be guided in a certain direction, thereby reducing the adhesion of the droplets. The cone angle 103 optimizes the flow path of the condensed droplets by changing the geometric shape of the edge of the mesh 102, so that the droplets can flow smoothly along the mesh 102 without staying on the surface of the mesh cover, thereby reducing the accumulation and adhesion of the droplets.

[0056] In a specific embodiment, the cone angle 103 is 20-80°.

[0057] At 20°, the edge of the mesh 102 is sharper, and the droplets will slide out of the edge of the mesh 102 more easily after condensation, reducing the residence time on the mesh surface. Therefore, the discharge effect of the droplets is faster, which helps to avoid the accumulation of droplets.

[0058] At 80°, the inclination angle of the edge of the mesh 102 is larger, the sharpness is lower, the guiding effect of the droplets is relatively mild, and the speed of the droplet flow is slower. At this time, it takes a long time for the condensed droplets to completely discharge from the mesh surface. Compared with a smaller cone angle 103 (such as 20°), a larger cone angle 103 makes the droplet flow more gently, and the interaction between the droplets and the mesh surface is weaker, so that the droplets are less likely to gather along the edge of the hole, but are more inclined to flow or drip in the vertical direction, thereby reducing the probability of droplet retention.

[0059] In some situations where stable airflow or uniform gas flow is required, the 80° cone angle 103 design has obvious advantages. The larger cone angle 103 makes the droplet flow more gentle, which can reduce the fluctuation and disturbance of the airflow, thereby maintaining the permeability and volatilization efficiency of the gas. For dense or low-volatile substances, the larger contact angle makes the flow of droplets more gentle and controllable, reduces the reverse flow of droplets, and avoids the accumulation and backflow of condensed droplets on the surface of the mesh, thereby improving the treatment effect of condensed substances.

[0060] Preferably, the cone angle 103 is 30°, 40°, 50°, 60° or 70°.

[0061] Preferably, the cone angle 103 is 35° or 45°.

[0062] In a specific embodiment, the opening rate of the mesh 102 of the volatilization area 101 is 70-95%. The opening rate of the mesh 102 of 70-95% ensures that the gas in the volatilization area 101 can quickly pass through the mesh cover, reducing the resistance of the airflow, so that the volatile substances can be quickly and evenly diffused to the external environment. For the protective mesh cover 1, this opening rate range can effectively meet the needs of efficient gas transmission and rapid volatilization. In other words, this high opening rate allows the volatile substances to be discharged more effectively, improves the volatilization efficiency, especially in the scene where rapid volatilization is required or the volatile gas is relatively dense, it can ensure that the volatile gas flows unimpeded.

[0063] refer to Figures 2 to 3 As shown, the mesh 102 with the cone angle 103 is a diamond mesh 102. The diamond mesh 102 is used to improve the geometric shape of the mesh 102, so that the cone angle 103 at the edge of the mesh 102 is more directional and sharper. The four sides of the diamond mesh 102 are relatively symmetrical. Compared with the circular mesh 102, the edges of adjacent holes of the diamond mesh 102 can be shared, thereby reducing the physical area of ​​the connection area. This structure helps to improve the guidance of the airflow and enhance the smoothness of the airflow.

[0064] Each edge of the diamond mesh 102 forms a relatively clear direction, which, when combined with the design of the cone angle 103, can reduce the retention of droplets while maintaining high permeability. When the droplets of condensed gas contact the edge of the mesh 102, the diamond geometry and its sharp edges of the mesh 102 can more effectively guide the flow of the droplets, avoid the accumulation of droplets near the mesh 102, and improve the droplet discharge efficiency.

[0065] Alternatively, the mesh 102 with the cone angle 103 is a regular quadrilateral mesh 102, such as a regular quadrilateral or a rectangle.

[0066] refer to Figure 4As shown, there is a liquid storage area 104. The liquid storage area 104 is formed by the connection of the adjacent mesh cone angles 103, and its shape is generally rectangular. In the vertical direction, the two sides of the liquid storage area 104 correspond to the corners of the cone angle 103. Therefore, the existence of the liquid storage area 104 makes the corner of the cone angle 103 become part of the rectangle, rather than forming a sharper angle, so that when the liquid flows along the edge of the cone angle 103 to this position, it will be temporarily blocked by the rectangular edge and then slowly slide down to the liquid storage area 104.

[0067] As an important component of the protective mesh cover 1, the liquid storage area 104 is mainly used to collect and store droplets condensed or remaining during the volatilization process. After the liquid condenses, it may accumulate on the surface of the mesh 102. Especially in a high temperature or high volatility environment, the condensed droplets may not be smoothly discharged due to unstable airflow or temperature changes. However, due to the guiding effect of the cone angle 103 of the mesh 103, the small droplets slide and gather along the edge of the hole, and finally slide into the liquid storage area 104. The setting of the liquid storage area 104 can effectively collect these droplets and prevent them from accumulating in the mesh 102, thereby ensuring the normal operation of the equipment.

[0068] In one embodiment, the liquid storage area 104 adopts a solid surface structure, which is effectively isolated from the surrounding environment to prevent the reflow or backflow of condensed droplets. This structure ensures that the droplets can stay therein until they are discharged or evaporated without negatively affecting the surrounding airflow and other volatilization processes. The design of the liquid storage area 104 specifically takes into account the storage needs of small droplets during the condensation process. These small droplets are often difficult to be guided by the cone angle 103, and the liquid storage area 104 can provide them with a temporary storage space to avoid the disordered flow of small droplets and affect the user experience.

[0069] refer to Figure 4 As shown, there is a thin-wall bridge 105. It should be understood that in the vertical direction, the thin-wall bridge 105 connects the adjacent liquid storage areas 104. In other words, the droplets in the liquid storage area 104 can further slide to the next liquid storage area 104 through the thin-wall bridge 105, and then finally slide to the bottom of the volatilization area to be collected. Of course, some small droplets will also adhere to the liquid storage area 104 and the thin-wall bridge 105, and then continue to volatilize or evaporate under the action of hot air.

[0070] When placed horizontally, the thin-wall bridge 105 can still effectively control the flow of droplets, preventing the droplets from gathering locally on the surface of the mesh and flowing in a certain direction. Specifically, the droplets sliding along the circumferential wall of the mesh will be divided into several small droplets by the thin-wall bridge 105, which on the one hand helps to continuously volatilize or evaporate under the action of hot air, and on the other hand reduces the aggregation of small droplets into large droplets, preventing large droplets from dripping directly.

[0071] In a specific implementation, there are multiple thin-wall bridges 105 , which are arranged parallel to each other.

[0072] The thin-wall bridge 105 should be understood as a thin-walled plate-like member with an elongated structure, which is arranged in the volatile area 101 of the protective mesh cover 1 and is used to connect and support a plurality of mesh holes 102 and liquid storage areas 104 located in the same column or row. The thin-wall bridge 105 is thin and strong, and can provide necessary support and dispersion without significantly increasing the overall weight or volume of the mesh cover.

[0073] refer to Figure 5 As shown, the protective mesh cover 1 has a connection area 106. The protective mesh cover 1 includes the connection area 106. The connection area 106 is located below the volatilization area 101 and extends in the vertical direction. The purpose of the connection area 106 is to connect the volatilization container 203, ensure that the volatilization container 203 is stably installed in the device, and facilitate the user to operate. Specifically, the volatilization container 203 can be pushed into the space enclosed by the connection area 106 by sliding, and can be stuck after reaching the specified position to prevent it from being displaced or falling off during use.

[0074] In this embodiment, one or more blocks are provided on the bottom side wall of the volatilization container 203, and a slot 1061 is provided at a corresponding position of the connection area 106. During the installation of the volatilization container 203, the user only needs to slide the volatilization container 203 into the connection area 106 along the vertical direction, and the blocks will cooperate and engage with the slot 1061. When the volatilization container 203 slides to a specified depth, the engagement of the blocks with the slot 1061 can effectively prevent the volatilization container 203 from going deeper, thereby ensuring that the volatilization container 203 is accurately installed in the correct position of the connection area 106.

[0075] Specifically, the shape and size of the card block are precisely matched with the card slot 1061, so that the volatilization container 203 can be easily slid in and aligned during the installation process. When the volatilization container 203 reaches the installation depth, the card block is blocked and fixed, which not only prevents the volatilization container 203 from moving due to vibration or external force, but also ensures that its position will not be offset.

[0076] The distance between the bottom of the volatilization container 203 and the bottom of the connection area 106 is set between 3 mm and 6 mm. This distance is set based on safety considerations to prevent children from easily pulling out the volatilization container 203 to protect the safety of children. Through this design, even if children operate it by mistake, it is not easy to directly touch the liquid inside the volatilization container 203, thereby avoiding the risk of accidental contact with the volatilization liquid.

[0077] Specifically, the distance is set between 3 mm and 6 mm to ensure the fixation of the volatilization container 203 during the installation process. Within this range, it is difficult for users (especially children) to easily pull out the volatilization container 203 by simply pulling or touching it, which increases safety. This design not only optimizes the performance of the device, but also provides additional child protection functions, effectively reducing the safety hazards caused by children's misoperation, and improving the family friendliness and safety of the product.

[0078] A guide groove 1062 is provided in the connection area 106. Correspondingly, when the protective mesh cover 1 is assembled to the portable electric volatile device 2, in order to achieve more accurate state control, a guide block is provided in the device housing of the portable electric volatile device 2, and the device housing and the connection area 106 of the protective mesh cover 1 are slidably matched. Generally speaking, the device housing includes a first shell and a second shell that are separable and dockable. A guide block is provided inside the second shell, and is slidably connected to the connection area 106. The guide groove 1062 is provided as a broken line in the axial direction of the protective mesh cover 1. The design of the broken line plays an important role: when the guide block slides along the broken line path, the change in the path will cause the guide block to be blocked, indicating that the second shell and the first shell are in the first separation state. In this state, the volatile area 101 is fully exposed, allowing the volatile liquid to enter the working state.

[0079] When the user rotates the second housing at a certain angle, the guide block moves along the changed path of the broken line path and gradually reaches the end point. At this time, the user can continue to pull the second housing circumferentially to completely separate it from the connection area 106, which is convenient for further operation or maintenance of the device.

[0080] In a specific embodiment, the connection area 106 of the protective mesh cover 1 is further provided with a first deformation block 1063. The purpose of the first deformation block 1063 is to ensure that the second housing can smoothly transition during the relative sliding process and accurately dock at the clamping position through a specific deformation mechanism, while avoiding the jamming phenomenon caused by excessive clamping force.

[0081] Specifically, the first deformation block 1063 is arranged in the connection area 106, and is designed to be deformed by the extrusion force during the sliding process of the second shell. Specifically, the first deformation block 1063 is formed by stamping the protective mesh cover 1, and has a small protrusion facing the second shell. Correspondingly, an adaptive groove is arranged inside the second shell, and the small protrusion and groove of the first deformation block 1063 can be snapped. When the second shell slides along the guide groove 1062, the first deformation block 1063 will be deformed inward due to external pressure, thereby allowing the second shell to continue to slide and pass through the first deformation block 1063. At this time, the first deformation block 1063 is temporarily in a deformed state to create space for the subsequent snap-on process.

[0082] When the second shell continues to slide and the slot inside it corresponds to the position of the first deformation block 1063, the first deformation block 1063 will restore its original shape after the external force is removed and complete the locking in the slot (set inside the second shell).

[0083] In order to ensure smooth and stable connection, the first deformable block 1063 is designed to ensure that the clamping force is not too large, so as to avoid the possibility of complete jamming caused by excessive clamping force, that is, to prevent the first deformable block 1063 from being too tightly clamped in the clamping slot, thereby affecting subsequent disassembly or operation.

[0084] The second deformable block 1064 is included. The second deformable block 1064 is used to clamp and fix the volatilization container 203. Specifically, the second deformable block 1064 is formed by stamping the protective mesh cover 1, and has a small protrusion facing the volatilization container 203. Correspondingly, the outer wall surface of the volatilization container 203 is provided with an adaptive groove. The small protrusion and the groove of the second deformable block 1064 can be clamped, so as to clamp and fix the volatilization container 203.

[0085] The connection area 106 is provided with an observation slot, and the second housing is provided with an observation window, so as to allow the user to conveniently understand the remaining amount of the volatile liquid in the volatile container 203, thereby effectively understanding the working status of the device.

[0086] refer to Figures 6 to 8 As shown, a portable electric volatile device 2 is provided. The portable electric volatile device 2 can be applied to mosquito repellent, insect repellent, or fragrance device.

[0087] The portable electric volatilization device 2 comprises:

[0088] An electric heating element 201, configured to be connected to a power supply element to provide heat energy;

[0089] Volatile core rod 202. The main function of the volatile core rod 202 is to be inserted into the volatile container 203 containing the volatile liquid and to make the volatile liquid produce capillary phenomenon.

[0090] As described in the above embodiment, the volatilization area 101 formed by the protective mesh cover 1 is used to enclose the volatilization core rod 202 .

[0091] The electric heating element 201 is used to provide heat energy to the volatile core rod 202 .

[0092] The electric heating element 201 and the volatilization core rod 202 are both located in the volatilization area 101 of the protective mesh cover 1. This configuration ensures that the entire heating and volatilization process is protected by the protective mesh cover 1. The protective mesh cover 1 effectively isolates the high temperature generated by the electric heating element 201 and the volatilization core rod 202, preventing the high temperature gas from directly affecting the external environment of the device or the user.
