Description

Technical Field

[0001] This utility model relates to the field of smart home technology, and in particular to a mattress with ventilation function. Background Technology

[0002] As an indispensable piece of bedding in daily life, the core function of a mattress is to provide support and comfort for the human body. Traditional mattresses mostly use materials such as springs, foam, and latex to meet basic support and cushioning needs. With technological advancements and consumers' increasing demands for sleep quality, the function of mattresses has gradually expanded from simple support to intelligent and health-oriented features. The ventilation performance of a mattress directly affects the user's comfort and hygiene. However, due to the dense materials or closed structure of traditional mattresses, heat and moisture can easily accumulate, potentially leading to the growth of bacteria and mites with long-term use, and even causing skin discomfort.

[0003] In the prior art, a breathable and ventilated mattress (publication number CN112641268A) achieves active ventilation by incorporating a ventilation layer and airflow guiding structure within the mattress, combined with bottom air inlets and top air outlets, and utilizing an external fan to drive air circulation. The bottom air inlets are connected to the fan, and the top air outlets are arranged in a grid pattern, designed to remove moisture and heat through forced airflow circulation. This design improves the breathability of traditional mattresses to some extent, and the enhanced airflow through mechanical ventilation can reduce surface humidity. However, such solutions still have significant limitations in practical applications.

[0004] First, the mattress needs to be placed on a bed frame or support. The space between the bottom air inlet and the support is usually quite narrow, leading to increased airflow resistance and a significant reduction in airflow efficiency. Second, while the top air outlet uses a uniformly distributed grid layout to achieve airflow coverage, the airflow speed is greatly weakened, making it difficult to create effective airflow perception. When the user lies down, the contact surface between the body and the mattress creates localized pressure, further hindering the penetration of the dispersed airflow and reducing ventilation. Furthermore, current technology uses bottom air intake, and the overall ventilation efficiency is insufficient to meet practical needs. Summary of the Invention

[0005] In order to overcome the shortcomings of low air intake efficiency and poor airflow dispersion, this utility model provides a mattress with ventilation function, aiming to solve the above-mentioned shortcomings.

[0006] A ventilated mattress includes a base plate with a frame attached to the top. Inside the frame, from bottom to top, are arranged partitions, a latex pad, and a sealing air cushion. The outer ring of the sealing air cushion is aligned with the frame. Each area separated by the sealing air cushion is connected to a ventilation pad, with the bottom of the ventilation pad suspended. A blower is installed on the inner front side of the frame, and a control panel is installed on the front side of the frame. One end of a duct is connected to the air outlet of the blower, and the other end of the duct extends along the mattress to the rear end of the frame, branching into several vertically upward-pointing ducts. The number of ducts is equal to the number of ventilation pads. Each duct passes through the partition and connects to a control valve and an air outlet. The control valve and the blower are wired to the control panel. The control valve is located inside the latex pad, and the air outlet is located between the ventilation pad and the sealing air cushion. A filter assembly for optimizing the air intake quality of the blower is provided at the front end of the frame.

[0007] As a preferred embodiment of this utility model, the filter assembly includes a filter box, the filter box is slidably connected to the front end of the frame, the filter box is through the front and rear and the rear end is connected to the air inlet of the blower, a filter layer is provided inside the filter box, two racks are slidably connected inside the filter box, a handwheel is rotatably connected to the front side of the filter box, a gear is connected to the rear end of the handwheel, the gear meshes with the racks, and the racks are respectively located on the upper and lower sides of the gear, and the two ends of the racks that are separated are slidably connected to the frame.

[0008] As a preferred embodiment of this utility model, a heating coil and a heat insulation sleeve are installed on the top of the air duct. The heating coil is located above the control valve, and the heat insulation sleeve wraps around the heating coil. The heat insulation sleeve is located inside the latex pad, and a temperature sensor is installed at the bottom of the sealing air pad. The temperature sensor is wired to the control panel.

[0009] As a preferred embodiment of this utility model, the blower inlet is connected to a sealing gasket.

[0010] As a preferred embodiment of this utility model, a filter screen is provided at the front opening of the filter box.

[0011] As a preferred technical solution of this utility model, the air outlet is provided with a plurality of air outlet holes around its side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Through the filter components and blower, the air drawn in by the blower is purified by multiple layers of activated carbon and filter cotton, and then evenly distributed to each branch pipe through the main air duct with a gradually narrowing cross section. The principle of fluid pressure equalization is used to reduce airflow transmission loss, significantly improve air intake efficiency, and ensure stable and sufficient airflow input to the bottom of the mattress.

[0014] 2. Through the zoned control design of the control valve and the air outlet, the control valve of a specific area can be selectively opened based on the user's lying position. After the airflow is delivered to the corresponding air outlet through the branch pipe, it is dispersed into multiple low-speed airflows by the air outlet holes distributed in a ring on the side wall, avoiding concentrated direct blowing on the human body.

[0015] 3. The bottom of the ventilation pad is suspended to form a buffer chamber. When the airflow diffuses upward, it further reduces the wind speed and expands the coverage area. Combined with the closed-loop temperature control of the temperature sensor and heating coil, it realizes the uniform distribution of local airflow and adaptive temperature adjustment. Users can clearly feel the dryness and temperature comfort brought by the ventilation function, which solves the pain point of "weak perception" of traditional decentralized air outlets.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0024] Example: A mattress with ventilation function, such as Figure 1 and Figure 2 As shown, the system includes a base plate 1, a frame 2, a partition 3, a latex pad 4, a sealing air pad 5, a venting air pad 6, a blower 9, an air duct 10, a control panel 101, a control valve 11, an air outlet 13, and a filter assembly. The frame 2 is connected to the top of the base plate 1. Inside the frame 2, from bottom to top, the partition 3, the latex pad 4, and the sealing air pad 5 are placed sequentially. The outer ring of the sealing air pad 5 is aligned with the frame 2. Each area separated by the sealing air pad 5 is connected to a venting air pad 6, with the bottom of the venting air pad 6 suspended. The blower 9 is installed on the inner front side of the frame 2, and the control panel 101 is installed on the front side of the frame 2. One end of the air duct 10 is connected to the air outlet of the blower 9. The other end of pipe 10 extends along the mattress to the rear end of frame 2, branching into several vertically upward-pointing pipes. The number of these branch pipes is equal to the number of air cushions 6, ensuring that each independent area has an independent airflow channel. Each branch pipe passes through partition 3 and connects to control valve 11 and air outlet 13. Control valve 11 and blower 9 are both wired to control panel 101. Control valve 11 is located inside latex pad 4, and air outlet 13 is located between air cushion 6 and sealing air cushion 5. Several air outlet holes are arranged around the side of air outlet 13. These annularly distributed air outlet holes disperse the concentrated airflow into multiple low-speed airflows, preventing direct airflow from the body and causing discomfort. After the airflow exits from the air outlet holes, it diffuses upwards along the suspended area at the bottom of air cushion 6, evenly covering the user's body surface, achieving localized ventilation and cooling or heating functions. A filter assembly is installed at the front end of frame 2 to optimize the air intake quality of blower 9.

[0025] like Figure 3 and Figure 6 As shown, the filter assembly includes a filter box 7, a filter interlayer 8, a handwheel 14, a gear 15, and a rack 16. The filter box 7 is slidably connected to the front end of the frame 2. The filter box 7 is open from front to back and its rear end is connected to the air inlet of the blower 9. The filter interlayer 8 is provided inside the filter box 7. The filter interlayer 8 is composed of multiple layers of activated carbon and filter cotton stacked alternately. The activated carbon adsorbs odors and volatile substances, while the filter cotton captures fine dust to ensure clean output airflow. Two racks 16 are slidably connected inside the filter box 7. The handwheel 14 is rotatably connected to the front side of the filter box 7. The gear 15 is connected to the rear end of the handwheel 14. The gear 15 meshes with the rack 16, and the racks 16 are located on the upper and lower sides of the gear 15, respectively. The two ends of the racks 16 that are separated are slidably connected to the frame 2. When the operator turns the handwheel 14, the gear 15 moves accordingly and drives the racks 16 on the upper and lower sides to retract towards the middle, disengaging from the locked state with the frame 2. The filter box 7 can be pulled out along the slide rail of the frame 2 to expose the internal filter interlayer 8 for cleaning or replacement.

[0026] like Figure 2 , Figure 4 and Figure 5As shown, it also includes a heating coil 12, a heat insulation sleeve 18, and a temperature sensor 19. The heating coil 12 and the heat insulation sleeve 18 are installed on the top of the air duct 10. The heating coil 12 is located above the control valve 11. The heat insulation sleeve 18 wraps around the heating coil 12 and is located inside the latex pad 4. The temperature sensor 19 is installed at the bottom of the sealing air pad 5. The temperature sensor 19 is wired to the control panel 101. The air outlet 13 has annularly distributed air outlet holes on its side wall, which disperse the concentrated airflow into multiple low-speed airflows to avoid direct airflow on the human body and cause discomfort. After the airflow is ejected from the air outlet, it diffuses upward along the suspended area at the bottom of the ventilation pad 6, evenly covering the user's body surface, realizing local ventilation and cooling or heating functions. The temperature sensor 19 at the bottom of the sealing air pad 5 monitors the airflow temperature in real time.

[0027] like Figure 3 As shown, it also includes a sealing gasket 17, and the air inlet of the blower 9 is connected to the sealing gasket 17.

[0028] like Figure 1 As shown, it also includes a filter screen 20. The filter box 7 has a filter screen 20 at the front opening, which intercepts large particulate impurities in the air.

[0029] The filter box 7 and control panel 101 are located at the foot of the bed. The sealing air mattress 5 divides the bed into ten zones, with different areas used by different people. The number of users and their height determine the zones used, allowing users to select the appropriate zone for ventilation. The sealing air mattress 5 divides the mattress surface into multiple independent zones. When a user lies down, the air mattress 6 in the area in contact with the body is compressed and sinks, with the suspended structure at the bottom forming an airflow buffer chamber. The air mattress 6 in the uncompressed areas maintains its original height, resulting in less resistance to airflow and maximizing ventilation efficiency. Through zone control, users can select the corresponding zone for ventilation based on their lying position, avoiding wasted airflow. By opening the control valve 11 at the bottom of the selected zone's air mattress 6 via the control panel 101, the blower 9 is turned on. The air drawn in by the blower 9 passes through the filter box 7, flows along the air duct 10 to each branch pipe, and is ejected from the branch pipe where the control valve 11 is opened. After passing through the air outlet 13, it diffuses in all directions and finally exits from the air mattress 6, blowing towards the user to achieve the ventilation function.

[0030] When airflow passes through filter box 7, it is purified by filter layer 8, thus ensuring that the gas sprayed from ventilator 6 will not affect the user even if it comes into direct contact with the user. Filter screen 20 can filter larger impurities and extend the service life of filter layer 8. After a period of use, the user turns handwheel 14, which drives gear 15 to rotate. The two racks 16 meshing with gear 15 slide towards the middle. After the racks 16 disengage from frame 2, they are pulled out of filter box 7 through handwheel 14 to clean or replace the internal filter layer 8, ensuring the filtration effect of airflow. After replacement, filter box 7 is pushed back in, and handwheel 14 is turned in the opposite direction. The racks 16 are reinserted into frame 2 to fix filter box 7. Filter box 7 is connected to blower 9. Sealing gasket 17 can optimize the sealing of the connection.

[0031] If the temperature is low, the user can activate the heating function via the control panel 101. The heating coil 12 heats the passing airflow, and the heat insulation sleeve 18 locks in the heat of the heating coil 12. The heated airflow is then ejected from the air outlet 13 and comes into contact with the temperature sensor 19. The temperature sensor 19 is set with a temperature range to prevent high temperatures from damaging the ventilation pad 6 and the sealing pad 5. If the temperature detected by the temperature sensor 19 is higher than the highest temperature of the set temperature range, it sends a high temperature signal to the control panel 101, and the control panel 101 turns off the heating coil 12 at the bottom of the temperature sensor 19. If the temperature detected by the temperature sensor 19 is lower than the lowest temperature of the temperature range, it sends a low temperature signal to the control panel 101, and the control panel 101 turns on the heating coil 12 at the bottom of the temperature sensor 19 to maintain a stable temperature.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
