Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a pillow. Background Technology

[0002] The existing pillow includes a pillow body and a mounting groove at the bottom of the pillow body for embedding a drug vaporization box. The pillow body has a ventilation pipe bridging the mounting groove and the top surface of the pillow body. The ventilation pipe includes inclined diffusion channels bridging the top wall of the mounting groove and the top surface of the pillow body. The lower ends of the diffusion channels are concentrated on the top wall of the mounting groove, while the upper ends are distributed in various areas of the top surface of the pillow body. Drug-laden gas generated in the drug vaporization box diffuses and is transported to various areas of the top surface of the pillow body through the diffusion channels for absorption by the user through respiration. Each diffusion channel is a straight tube, and its length varies depending on the relative positions of its upper and lower ends. This variation in channel length creates varying airflow resistance, preventing the drug-laden gas from diffusing evenly to all areas of the pillow body. Furthermore, the different axial directions of the diffusion channels increase manufacturing difficulty and negatively impact the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pillow with a horizontal diffusion cavity. The horizontal diffusion cavity, which is connected to the mounting groove and is in a grid pattern, is set in the middle of the pillow body. This not only allows for the horizontal diffusion of the drug-carrying gas, but also facilitates processing and improves the user experience.

[0004] This invention is achieved through the following method: a pillow with a horizontal diffusion cavity, comprising a pillow body and a drug vaporization box disposed at the bottom of the pillow body. The pillow body has a horizontal diffusion cavity adjacent to the drug vaporization box and a vertical channel bridging the horizontal diffusion cavity and the top surface of the pillow body. The horizontal diffusion cavity is grid-shaped. Drug-laden gas generated in the drug vaporization box diffuses horizontally through the horizontal diffusion cavity and is transported to the space above the pillow body through the corresponding vertical channel. A grid-shaped horizontal diffusion cavity is disposed in the middle of the pillow body, communicating with the mounting groove. Each area of ​​the horizontal diffusion cavity is connected to a corresponding area on the top surface of the pillow body through vertical channels. This effectively reduces the axial length difference between the vertical channels, thereby ensuring uniform diffusion of the drug-laden gas by balancing airflow resistance. It also allows the drug-laden gas in the mounting groove to be evenly diffused to various areas in the middle of the pillow body, and then diffused upwards through the corresponding vertical channels. Furthermore, the grid-shaped horizontal diffusion cavity can be formed by horizontal and vertical openings, facilitating manufacturing and improving the user experience.

[0005] Preferably, the horizontal diffusion cavity includes interleaved transverse and longitudinal channels. The transverse and longitudinal channels are perpendicularly connected and located in the same horizontal plane, which facilitates the flow and diffusion of the drug-carrying gas between adjacent transverse and longitudinal channels, thereby ensuring a uniform concentration of drug-carrying gas in each region of the horizontal diffusion cavity. It also effectively reduces processing difficulty and facilitates production.

[0006] Preferably, the vertical channels are evenly distributed on the pillow body, with the lower port of each vertical channel connecting to the corresponding horizontal and vertical channels, and the upper port exposed on the top surface of the pillow body. The drug-carrying gas in the horizontal diffusion chamber can be transported upwards through the vertical channels. The lower port of the vertical channel is located at the intersection of the horizontal and vertical channels, facilitating the simultaneous reception of drug-carrying gas from both channels, thereby improving the diffusion efficiency of the drug-carrying gas.

[0007] Preferably, the transverse channels are multiple and parallel, and the longitudinal channels are also multiple and parallel, which not only provides the drug-carrying gas to the evenly spaced vertical channels but also effectively improves the diffusion uniformity of the horizontal diffusion cavity. The transverse and longitudinal channels can exchange air with the outside environment through exposed ports, thereby driving the drug-carrying gas to diffuse rapidly within the horizontal diffusion cavity, improving diffusion efficiency and uniformity.

[0008] Preferably, the two ends of the transverse channel are exposed on the corresponding sidewalls of the pillow body, and the two ends of the longitudinal channel are exposed on the corresponding sidewalls of the pillow body. Preferably, the pillow body is a one-piece structure, and the vertical, transverse, and longitudinal channels are all linear channels. This facilitates the formation of a horizontal diffusion cavity within the one-piece pillow body by creating through-type transverse and longitudinal channels, effectively improving processing efficiency.

[0009] Preferably, the drug vaporization box is exposed within the horizontal diffusion cavity through a diffusion hole on its top surface, allowing the horizontal diffusion cavity to receive drug-laden gas from the diffusion hole and convey it to the vertical channel. The drug-laden gas generated within the drug vaporization box diffuses outward through the diffusion hole and enters the horizontal diffusion cavity.

[0010] Preferably, the pillow body is a split structure, comprising a lower layer and an upper layer. The bottom surface of the upper layer and the top surface of the lower layer are vertically stacked and enclosed to form the horizontal diffusion cavity. The upper layer and the lower layer are processed independently and then stacked and bonded to form the pillow body. At least one of the bottom surface of the upper layer and the top surface of the lower layer has a concave-convex surface, so that the two layers can enclose the horizontal diffusion cavity after being stacked and fixed together, thereby reducing the processing difficulty.

[0011] Preferably, the bottom surface of the upper layer has square protrusions arranged in a matrix. The upper layer is attached to and enclosed by the bottom surface of the square protrusions and the top surface of the lower layer to form the horizontal diffusion cavity. The bottom surface of the upper layer overlaps the top surface of the lower layer through the square protrusions, and the space between adjacent square protrusions is blocked by the top surface of the lower layer to form the horizontal diffusion cavity.

[0012] Preferably, the front and rear edges of the top surface of the lower layer are raised upwards to form a front limiting strip and a rear limiting strip, respectively. The upper layer overlaps the lower layer and is secured between the front and rear limiting strips by square protrusions. The square protrusions are all positioned in the area between the front and rear limiting strips and abut against the center of the top surface of the lower layer. The front and rear limiting strips effectively limit the upper layer in a forward and backward direction, and also effectively prevent the leakage of medicated gas through the front and rear edges of the pillow body.

[0013] Preferably, the top surface of the lower layer is bonded and fixed to the bottom surface of the upper layer through a hot-melt layer. The hot-melt layer completely covers the top surface of the lower layer, which not only serves to bond and fix the upper and lower layers, but also seals the bottom wall of the horizontal diffusion cavity, preventing the drug-carrying gas from diffusing and leaking downward through the lower layer, and ensuring that the drug-carrying gas can be transferred upward.

[0014] Preferably, the square protrusions located on the side edges of the bottom surface of the upper layer are cuboid in shape, while the square protrusions located in the center of the bottom surface of the upper layer are cube-shaped. The cuboid square protrusions on the side edges of the pillow body improve the support reliability of the side edges, thereby enhancing the deformation resistance and preventing excessive deformation of the side edges due to stress. The cube-shaped square protrusions in the center of the pillow body allow the two opposing sidewalls of the square protrusions to form the sidewalls of adjacent transverse or longitudinal channels, ensuring that adjacent transverse or longitudinal channels remain parallel and have the same spacing, thus improving the uniformity of drug-carrying gas diffusion in the horizontal diffusion cavity.

[0015] Preferably, the lower layer has a vertically penetrating mounting groove in the middle, and the drug vaporization box is inserted and fixed in the mounting groove from bottom to top, so that the top surface of the drug vaporization box is exposed in the horizontal diffusion cavity. The mounting groove is vertically penetrating in the middle of the lower layer, which not only ensures that the top of the mounting groove is connected to the horizontal diffusion cavity, but also facilitates the installation and removal of the drug vaporization box through the bottom of the mounting groove.

[0016] Preferably, the drug evaporation box includes a base with a drug-carrying module and a cover ring with a pressure plate. A gravity switch assembly is provided below the pressure plate and is linked thereto. The gravity switch assembly includes an evaporation plate connected to the base and having evaporation holes, and an elastic switch with a switch hole. The elastic switch has a raised center that forms an elastic part that is fixed to the pressure plate, and switch parts with evaporation holes that can be translated along the top surface of the evaporation plate are formed on both sides. The pressure plate is lowered by force and the elastic part that deforms drives the switch parts to translate, so that the gravity switch assembly switches from a closed state where the switch hole and the evaporation hole are misaligned and blocked to an open state where the switch hole and the evaporation hole are aligned and connected. The flexible switch can drive the switch part to move and switch to the open state when the pressure plate is pressed down, so that the drug-containing gas in the shell can be released outward through the open switch assembly. It can also use the flexible part to drive the switch part to reset and block the evaporation hole, so that the opening and closing state of the switch assembly is related to the force state of the pressure plate, ensuring that the drug evaporation box will not be triggered when the user is not using the pillow, effectively improving the utilization efficiency of the drug module in the shell.

[0017] Preferably, the top surface of the evaporation plate is provided with guide grooves on both sides of the top surface, which have openings facing each other and allow the two sides of the switch part to be inserted into the plate. This guides the switch part to move along a preset path. The two sides of the switch part can move back and forth along the guide grooves, which ensures that the switch part will not detach from the evaporation plate and that the switch part can move accurately along the preset path, thereby ensuring the reliability of the switch assembly in opening and closing.

[0018] Preferably, the inner edge of the top surface of the cover ring is provided with a limiting ring, and the periphery of the pressure plate is provided with a limiting edge. The top surface of the limiting edge abuts against the bottom surface of the limiting ring and restricts the pressure plate from detaching from the cover ring. The limiting ring acts as abutment and limiting force against the limiting edge, preventing the pressure plate from detaching from the cover ring under the pushing force of the elastic switch.

[0019] The beneficial effects of this utility model are as follows: A horizontal diffusion cavity in a grid shape is provided in the middle of the pillow body and is connected to the mounting groove. Each area of ​​the horizontal diffusion cavity is connected to the corresponding area on the top surface of the pillow body through vertical channels. This effectively reduces the axial length difference between the vertical channels, thereby ensuring uniform diffusion of the drug-carrying gas by balancing the airflow resistance. It can also use the horizontal diffusion cavity to evenly diffuse the drug-carrying gas in the mounting groove to each area in the middle of the pillow body, and then diffuse upward through the corresponding vertical channels. Furthermore, the grid-shaped horizontal diffusion cavity can be formed by processing through horizontal and vertical openings, which facilitates processing and improves the user experience.

[0029] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] This embodiment provides a pillow.

[0032] like Figure 1 and 2The pillow shown includes a pillow body 1 and a drug vaporization box 2 disposed at the bottom of the pillow body 1. The pillow body 1 has a horizontal diffusion cavity adjacent to the drug vaporization box 2 and a vertical channel 3 spanning the horizontal diffusion cavity and the top surface of the pillow body 1. The horizontal diffusion cavity is grid-shaped. The drug-laden gas generated in the drug vaporization box 2 diffuses horizontally through the horizontal diffusion cavity and is transported to the space above the pillow body 1 through the corresponding vertical channel 3. A grid-shaped horizontal diffusion cavity is disposed in the middle of the pillow body 1, communicating with the mounting groove 13. Each area of ​​the horizontal diffusion cavity is connected to the corresponding area on the top surface of the pillow body 1 through the vertical channel 3. This effectively reduces the axial length difference between the vertical channels 3, thereby ensuring uniform diffusion of the drug-laden gas by balancing airflow resistance. It also allows the drug-laden gas in the mounting groove 13 to be evenly diffused to various areas in the middle of the pillow body 1, and then diffused upwards through the corresponding vertical channel 3. Furthermore, the grid-shaped horizontal diffusion cavity can be formed by horizontal and vertical openings, facilitating manufacturing and improving the user experience.

[0033] In this embodiment, the horizontal diffusion cavity includes interleaved transverse channels 5 and longitudinal channels 6. The transverse channels 5 are multiple and are parallel and equidistant from each other, and the longitudinal channels 6 are multiple and are parallel and equidistant from each other, so that the transverse channels 5 and longitudinal channels 6 are interconnected to form a grid structure. The vertical channels 3 are arranged in a matrix on the pillow body 1, and the lower port of each vertical channel 3 is connected to the intersection of the corresponding transverse channel 5 and longitudinal channel 6, so that the vertical channel 3 can simultaneously receive the drug-laden gas from the transverse channels 5 and longitudinal channels 6 and diffuse it upward.

[0034] In this embodiment, the upper port of the vertical channel 3 is exposed on the top surface of the pillow body 1, and the lower port is connected to the horizontal diffusion cavity. The lower layer 7 has a vertically penetrating mounting groove 13 in the middle. The drug evaporation box 2 is inserted and fixedly connected to the mounting groove 13 from bottom to top. The horizontal diffusion cavity is connected to the top of the mounting groove 13 (e.g., ...). Figure 6 As shown in the diagram, the top surface of the drug vaporization box 2 is exposed within the horizontal diffusion cavity. The drug vaporization box 2 is exposed within the horizontal diffusion cavity through a diffusion hole 4 on its top surface, allowing the horizontal diffusion cavity to receive the drug-laden gas from the diffusion hole 4 and transport it to the vertical channel 3. In use, the drug-laden gas generated by the drug vaporization box 2 is first transported to the horizontal diffusion cavity and then diffuses horizontally along the transverse channel 5 and longitudinal channel 6 to various areas of the pillow body 1. It then diffuses upwards through the corresponding vertical channel 3, ensuring that all areas above the pillow body 1 are covered by the diffused drug-laden gas, thus facilitating absorption by the user and promoting sleep and relieving snoring.

[0035] In this embodiment, the pillow body 1 is a split structure, including a lower layer 7 and an upper layer 8. The bottom surface of the upper layer 8 and the top surface of the lower layer 7 are vertically stacked and enclosed to form the horizontal diffusion cavity. The upper layer 8 and the lower layer 7 are independently processed and assembled to form the pillow body 1. The top surface of the lower layer 7 is bonded to the bottom surface of the upper layer 8 through a heat-fused layer 12, which not only ensures a firm connection between the upper layer 8 and the lower layer 7, effectively restricts relative displacement between the upper layer 8 and the lower layer 7, and ensures that the contour of the pillow body 1 remains constant, but also facilitates processing and improves production efficiency. The heat-fused layer 12 not only serves to bond the upper layer 8 and the lower layer 7, but also has a sealing function to prevent drug-carrying gas from diffusing into the lower layer 7, thereby improving drug utilization efficiency. The heat-fused layer 12 completely covers the top surface of the lower layer 7 and has an opening in the middle for the upper port of the mounting groove 13 to be exposed, ensuring that drug-carrying gas can smoothly pass through the heat-fused layer 12 and enter the horizontal diffusion cavity. Furthermore, the upper layer 8 and the lower layer 7 can also be directly fixed by adhesive, which should also be considered as a specific implementation of this embodiment.

[0036] In this embodiment, the bottom surface of the upper layer 8 is processed to form square protrusions 9 arranged in a matrix (e.g., Figure 3 As shown, when the upper layer 8 is stacked on the lower layer 7, the bottom surface of the square protrusion 9 and the top surface of the lower layer 7 are attached and enclosed to form the horizontal diffusion cavity, which facilitates the processing of the horizontal diffusion cavity and improves processing efficiency by reducing the processing difficulty.

[0037] In this embodiment, the front and rear edges of the top of the lower layer 7 rise upwards to form a front limiting strip 10 and a rear limiting strip 11, respectively. The upper layer 8 overlaps the lower layer 7 and is secured between the front limiting strip 10 and the rear limiting strip 11 by a square protrusion 9. The heights of the front limiting strip 10 and the rear limiting strip 11 match the height of the square protrusion 9, so that the top surfaces of the front limiting strip 10 and the rear limiting strip 11 simultaneously abut and seal against the bottom surfaces of the front and rear edges of the upper layer 8, and the bottom surface of the square protrusion 9 simultaneously abuts against the center of the top surface of the lower layer 7, forming a horizontal diffusion cavity with a transverse channel 5 and a longitudinal channel 6. Furthermore, the front limiting strip 10, the rear limiting strip 11, and the square protrusion 9 are located at the same height of the pillow body 1, which facilitates the mutual abutment to provide front-to-back positioning for the upper layer 8 and the lower layer 7, thereby ensuring that the outline of the upper layer 8 and the lower layer 7 remains constant after stacking.

[0038] In this embodiment, the square protrusion 9 located on the side edge of the bottom surface of the upper layer 8 is cuboid, and the square protrusion 9 located in the middle of the bottom surface of the upper layer 8 is cube-shaped. The cuboid-shaped square protrusions 9 are provided at both ends of the pillow body 1 in the width direction to improve the support reliability of the side edge of the pillow body 1, thereby improving its resistance to deformation and preventing excessive deformation of the side edge of the pillow body 1 due to stress. The cube-shaped square protrusion 9 is provided in the middle of the pillow body 1 so that the two opposite sidewalls of the square protrusion 9 can form the sidewalls of adjacent transverse channels 5 or adjacent longitudinal channels 6, and ensure that adjacent transverse channels 5 or adjacent longitudinal channels 6 remain parallel and have the same spacing (e.g., ...). Figure 4 and 5 As shown in the figure, this improves the uniformity of diffusion of the drug-carrying gas in the horizontal diffusion cavity.

[0039] In this embodiment, various drugs, such as traditional Chinese medicine, essential oils, and aromatherapy, can be placed in the drug evaporation box 2. The drug form can be solid, paste, or even liquid. When the drug is liquid, it can be mixed with cotton fibers to form a liquid-carrying cotton ball. All of these should be considered as specific implementation methods of this embodiment.

[0040] Example 2:

[0041] Compared to Example 1, this example provides another type of pillow.

[0042] like Figure 7 As shown, a drug evaporation box 2 is installed at the bottom of the pillow body 1. The drug evaporation box 2 includes a base 15 with a drug-carrying module 14 inside and a cover ring 17 with a pressure plate 16. A gravity switch assembly is provided below the pressure plate 16 and is linked thereto. The gravity switch assembly includes an evaporation plate 19 connected to the base 15 and having an evaporation hole 18, and an elastic switch 21 with a switch hole 20. The elastic switch 21 has a raised center that forms an elastic part that is fixed to the pressure plate 16. Switch parts with evaporation holes 18 are formed on both sides that can be translated along the top surface of the evaporation plate 19. The pressure plate 16 is lowered by force and the switch parts are driven to translate by the deformed elastic parts, so that the gravity switch assembly switches from a closed state where the switch hole 20 and the evaporation hole 18 are misaligned and blocked to an open state where the switch hole 20 and the evaporation hole 18 are aligned and connected. The elastic switch 21 serves two purposes: firstly, it receives the downward pressure from the pressure plate 16 and drives the switch section to move horizontally, allowing the switch assembly to switch from a closed state to an open state, ensuring the outward diffusion of the drug-laden gas; secondly, it utilizes its own elastic restoring force to drive the switch section and the pressure plate 16 to perform horizontal and vertical resets, respectively, allowing the switch assembly to switch from an open state to a closed state. This ensures that the opening and closing of the switch assembly is correlated with the force state of the pressure plate 16, and consequently with the user's usage state. During use, the user lies on the top surface of the pillow body 1, causing the pillow body 1 to deform and transmit a downward pressure force to the pressure plate 16, thereby triggering the switch assembly.

[0043] In this embodiment, the vertical cross-section of the elastic switch 21 is Ω-shaped, including an arc-shaped elastic part and a flat switch part on both sides of the elastic part. The top surface of the evaporation plate 19 is provided with guide grooves 22 with openings facing each other for the two sides of the switch part to be inserted. The two edges of the switch part can be slidably locked in the corresponding guide grooves 22, which can guide the switch part to move along a preset path and prevent the elastic switch 21 from detaching from the evaporation plate 19.

[0044] In this embodiment, a limiting ring 23 is provided on the inner edge of the top surface of the cover ring 17, and a limiting edge 24 is provided on the periphery of the pressure plate 16. The top surface of the limiting edge 24 abuts against the bottom surface of the limiting ring 23 and restricts the pressure plate 16 from detaching from the cover ring 17. The evaporation plate 19 is elongated and has at least three elastic switches 21 arranged along its length to ensure that the pressure plate 16 can rise and fall smoothly in a horizontal posture. The limiting edge 24 located at the edge of the pressure plate 16 can vertically abut against the limiting ring 23, thereby vertically limiting the pressure plate 16 and preventing the pressure plate 16 from detaching upward from the cover ring 17 under the drive of the elastic switches 21.

[0045] The other structures and effects of the pillow described in this embodiment are the same as those in Embodiment 1.

[0046] Example 3:

[0047] Compared to Embodiment 1 or 2, this embodiment provides another type of pillow.

[0048] like Figure 8 As shown, the pillow body 1 is a one-piece structure, and the vertical channel 3, the horizontal channel 5, and the longitudinal channel 6 are all linear channels. The vertical channel 3, the horizontal channel 5, and the longitudinal channel 6 are formed by opening through holes in the one-piece pillow body 1, which facilitates processing and also improves the structural strength of the pillow body 1.

[0049] In this embodiment, the two ends of the transverse channel 5 are exposed on the corresponding side wall of the pillow body 1, and the two ends of the longitudinal channel 6 are exposed on the corresponding side wall of the pillow body 1. This facilitates the formation of the channel through the opening and ensures that the transverse channel 5 and the longitudinal channel 6 can diffuse the drug-carrying gas outward through the two ends.

[0050] The other structures and effects of the pillow described in this embodiment are the same as those in Embodiment 1 or 2.
