Description

Technical Field

[0001] The present invention relates to the technical field of mattresses, and in particular to an air-heating mattress and an air-channel connector thereof. Background Art

[0002] In daily life, the most widely used heating devices for bed heating are electric blankets and water heating pads; however, electric blankets have the risk of electric leakage and are prone to cause local overheating, electromagnetic radiation and other unsafe factors. Water heating pads have many problems such as leakage, blockage, the need to take antifreeze measures and regular water replenishment, which are inconvenient to use and maintain.

[0003] In order to solve the above problems, Chinese patent CN208725264U discloses a cooling and heating pad that uses cold or hot air to cool or heat, including a pad body, an air supply device, an air supply pipeline arranged in the pad body, and a plug-in connector that connects the pad body, the air supply pipeline and the air supply device.

[0004] However, the portion of the plug connector close to the air supply device has higher heat, and since the distance between the plug connector and the surface of the cushion is small, the user may feel higher heat when lying on the cushion or touching the surface of the cushion with his hands, causing discomfort or even burns. Summary of the invention

[0005] The purpose of the present invention is to provide an air duct connector for an air-heating mattress, which can solve the problems existing in the prior art.

[0006] In order to achieve the above object, the technical solution of the present invention is:

[0007] An air duct connector for an air-heating mattress, comprising:

[0008] a first shell;

[0009] The first shell is provided with a first air inlet and a first air outlet, the first air inlet is connected to the air supply device, and the first air outlet is connected to the air supply duct of the air-heating mattress, so that the inner cavity of the first shell forms a warm air cavity;

[0010] The air duct connector also includes a second shell sleeved on the outside of the first shell;

[0011] A cavity is provided between the second shell and the first shell, and the cavity forms a heat-insulating cavity.

[0012] The air path connector of the air-heating mattress of the present invention forms a warm air cavity in the inner cavity of the first shell by arranging a first air inlet connected to the air supply device and a first air outlet connected to the air supply duct of the air-heating mattress on the first shell; and then a second shell is sleeved on the outside of the first shell, and an insulating cavity is provided between the second shell and the first shell. The insulating cavity is a cavity, which can prevent the heat in the warm air cavity from being conducted to the surface of the mattress, thereby preventing the user from feeling uncomfortable or being burned due to the excessively high surface temperature of the mattress.

[0013] As one specific implementation method, the insulation cavity may be hollow, or insulation material or heat dissipation material may be placed in the insulation cavity; the insulation cavity may also be sealed and vacuum-treated to achieve better insulation effect of the insulation cavity.

[0019] As one specific implementation manner, a duct installation opening corresponding to the first air outlet is provided on the second shell, and the duct connection portion extends out of the second shell from the duct installation opening.

[0020] Furthermore, a gap between the air duct connecting portion and the air duct mounting opening is smaller than a tube wall thickness of the air supply duct of the air-heating mattress.

[0021] The air duct connector of the air-heating mattress of the present invention makes the gap between the air duct connecting part and the air duct mounting opening smaller than the tube wall thickness of the air supply duct of the air-heating mattress. The air supply duct is generally made of rubber material or plastic, so that the air supply duct is fixed after being inserted into the gap between the air duct connecting part and the air duct mounting opening.

[0022] As one specific implementation manner, the cross section of the first shell in the horizontal direction is arranged in a square shape;

[0023] A plurality of the first air outlets are arranged on the side wall of the first shell, and the plurality of the first air outlets are located on the same horizontal plane.

[0024] The air duct connector of the air-heating mattress of the present invention makes the cross-section of the first shell in the horizontal direction square, so that the distance between the multiple first air outlets and the first air inlet arranged on the side wall of the first shell is close, so that the air volume flowing out from each first air outlet is evenly distributed; and the multiple first air outlets are on the same horizontal plane, so that the air supply ducts can be on the same horizontal plane and extend outward, thereby reducing the space inside the mattress to be occupied by the air supply ducts.

[0025] Another object of the present invention is to provide a wind-heated mattress, comprising:

[0026] A mattress body, a plurality of air supply ducts arranged in the mattress body, an air supply device, and the above-mentioned air duct connector.

[0027] As one specific implementation, a main air heating channel and a branch air heating channel are provided in the mattress body. The main air heating channel is arranged along the width direction of the mattress body, and a plurality of branch air heating channels are arranged equidistantly along the length direction of the mattress body.

[0028] Furthermore, the air duct connector is arranged in the middle position of the main air heating channel, one end of a plurality of the air supply ducts is respectively connected to the air duct connector, and the other end extends into the corresponding branch air heating channel along the main air heating channel.

[0029] The air-heating mattress of the present invention sets a main air-heating channel and multiple branch air-heating channels in the penetration point, and the main air-heating channel is arranged along the width direction of the mattress body, and the multiple branch air-heating channels are arranged equidistantly along the length direction of the mattress body, and then the air path connecting piece is set in the middle position of the main air-heating channel, so that each air supply duct extends to the front end and both sides with the air path connecting piece as the center and is evenly arranged in the mattress body, so that the air volume and heat delivered by each air supply duct are uniform, the temperature of each part of the mattress is kept uniform, and the user experience is higher.

[0030] Furthermore, the air supply device is provided with a first fan, a second fan and a heater;

[0031] The first fan is used to draw air from the outside and send it into the insulation cavity, and the second fan is used to draw air from the insulation cavity and send it into the warm air cavity through the heater.

The insulating cavity is a cavity, which can prevent the heat in the warm air cavity from being conducted to the surface of the mattress, thereby preventing the user from feeling uncomfortable or being burned due to the excessively high surface temperature of the mattress.

[0047] Specifically, the heat-insulating cavity 201 may be hollow, and heat-insulating materials or heat-dissipating materials may be placed in the heat-insulating cavity 201 ; the heat-insulating cavity 201 may also be sealed and vacuum-treated to achieve better heat-insulating effects of the heat-insulating cavity 201 .

[0048] It should be noted that if Figure 3 As shown, the first housing 10 described in this embodiment has a plurality of support blocks 104 disposed on its outer wall; Figure 2 As shown, when the first shell 10 is sleeved in the second shell 20 , the support block 104 contacts the inner wall of the second shell 20 , so that a cavity is formed between the second shell 20 and the first shell 10 .

[0049] Preferably, if Figure 3 As shown, a protruding air duct connecting portion 105 is provided at the first air outlet 12, and the air duct connecting portion 105 is interference-fitted with the air supply air duct.

[0050] The air path connector of the air-heating mattress of this embodiment is provided with a protruding air duct connecting part at the first air outlet, so that the air supply air duct in the mattress can be sleeved on the air duct connecting part and connected to the first air outlet more conveniently.

[0053] The air duct connector of the air-heating mattress of this embodiment is configured such that the gap between the air duct connecting portion and the air duct mounting opening is smaller than the wall thickness of the air supply duct of the air-heating mattress. The air supply duct is generally made of rubber material or plastic, so that the air supply duct is fixed after being inserted into the gap between the air duct connecting portion and the air duct mounting opening.

[0054] It should be noted that the second shell 20 of the present embodiment is composed of an upper shell and a lower shell, both of which are provided with semicircular holes; during installation, the air supply duct can be firstly put on the air duct connecting part 105, and then the upper and lower shells cover the first shell, so that the semicircular holes of the upper and lower shells clamp the air supply duct and combine to form the air duct installation port 106.

[0056] The air duct connector of the air-heating mattress of the present embodiment is configured such that the cross-section of the first shell in the horizontal direction is square, so that the distances between the plurality of first air outlets and the first air inlet arranged on the side wall of the first shell are close, thereby making the air volume flowing out of each first air outlet evenly distributed; and the plurality of first air outlets are on the same horizontal plane, so that the air supply ducts can be on the same horizontal plane and extend outward, thereby reducing the space inside the mattress to be occupied by the air supply ducts.

[0057] Another object of this embodiment is to provide a wind-heated mattress, which comprises:

[0058] like Figure 4 As shown, a mattress body 1, a plurality of air supply ducts 2 arranged in the mattress body 1, an air supply device 3, and the above-mentioned air duct connector 4.

[0059] Specifically, a main air heating channel 11 and a branch air heating channel 12 are provided in the mattress body 1 . The main air heating channel 11 is arranged along the width direction of the mattress body 1 , and a plurality of branch air heating channels 12 are arranged equidistantly along the length direction of the mattress body 1 .

[0060] Preferably, the air duct connector 4 is arranged in the middle position of the main air heating channel 11, and one end of a plurality of the air supply ducts 2 is respectively connected to the air duct connector 4, and the other end extends into the corresponding branch air heating channel 12 along the main air heating channel 11.

[0061] The air-heating mattress of this embodiment is provided with a main air-heating channel and multiple branch air-heating channels in the mattress, and the main air-heating channel is arranged along the width direction of the mattress body, and the multiple branch air-heating channels are arranged equidistantly along the length direction of the mattress body, and then the air path connecting piece is arranged in the middle position of the main air-heating channel, so that each air supply duct extends to the front end and both sides with the air path connecting piece as the center and is evenly arranged in the mattress body, so that the air volume and heat delivered by each air supply duct are uniform, the temperature of each part of the mattress is kept uniform, and the user experience is higher.

[0062] It should be noted that a plurality of air supply holes are evenly arranged on the air supply duct 2 in this embodiment.

[0063] Example 2

[0064] The main differences between this embodiment and embodiment 1 are:

[0065] The second shell 20 is provided with a second air inlet 202, and the second air inlet 202 is communicated with the heat insulation cavity 201;

[0066] like Figure 5 As shown, the air supply device 3 is provided with a warm air outlet 303, and the warm air outlet 303 is connected to the first air inlet 101;

[0067] The air supply device 3 is further provided with a cold air outlet 301 , and the cold air outlet 301 is connected to the second air inlet 202 .

[0068] It should be noted that if Figure 1 As shown, the second shell 20 also includes an air vent panel 203 , and the second air inlet 202 is arranged on the air vent panel 203 and directly communicated with the heat insulation cavity 201 ; the air vent panel 203 is also provided with an opening, which is sealed and connected to the first air inlet 101 .

[0069] In addition, a second air outlet 204 is provided on the air outlet panel 203 , and the air entering the heat insulation cavity 21 from the second air inlet 202 is discharged from the second air outlet 204 , so that a smooth airflow is formed in the heat insulation cavity 21 .

[0070] The air path connector of the air-heated mattress of the present embodiment is configured with a second air inlet connected to the heat-insulating cavity on the second shell, and the second air inlet is connected to the cold air outlet of the air supply device. The air supply device continuously injects air with a lower temperature than the air in the warm air cavity into the heat-insulating cavity, thereby continuously taking away the heat conducted into the heat-insulating cavity from the first shell, and further reducing the heat on the surface of the air path connector.

[0071] It should be noted that the air supply device 3 is provided with a first fan for supplying air to the heat insulation cavity 201 and a second fan for supplying air to the warm air cavity 103 .

[0072] Example 3

[0073] The main differences between this embodiment and embodiment 2 are:

[0074] The air supply device 3 is provided with a first fan, a second fan and a heater 304;

[0075] The first fan is used to draw air from the outside and send it into the insulation chamber 201, and the second fan is used to draw air from the insulation chamber 201 and send it into the warm air chamber 103 through the heater.

[0076] In the air-heated mattress of this embodiment, the first fan of its air supply device first draws air from the outside and sends it into the insulation cavity. Since the outside air is usually at room temperature or low temperature, it will take away the heat in the insulation cavity when flowing through the insulation cavity, that is, this part of the air is preheated when passing through the insulation cavity; then the second fan draws in this part of the preheated air, and sends it into the warm air cavity after being heated by the heater; that is to say, the air passing through the insulation cavity, while taking away the heat conducted from the first shell to the insulation cavity, is also preheated using the heat in the insulation cavity. The heater in the air supply device can appropriately reduce the output power, thereby reducing the energy consumption of the air supply device and saving the user's electricity costs.

[0077] It should be noted that, without affecting understanding, the internal structure schematic diagram of the air supply device 3, the structural schematic diagram of the first fan and the second fan are not shown in the drawings.

[0078] like Figure 5 As shown, the air supply device 3 is provided with a cold air outlet 301, a cold air return outlet 302 and a warm air outlet 303;

[0079] The cold air outlet 301 is connected to the second air inlet 202 on the second shell, the cold air return port 302 is connected to the second air outlet 204 on the second shell, and the warm air outlet 303 is connected to the first air inlet 101 on the first shell.
