Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, specifically relating to a pet bed. Background Technology

[0002] With the increasing number of people keeping pets such as cats and dogs, pet beds are commonly used to provide a comfortable resting environment for pets at home. This prevents pets from sitting or lying directly on the ground, which can lead to illness from being too cold or too hot. Since pets mostly live indoors, their living environment is generally influenced by their owners' environment. For example, air conditioning is used for cooling in summer and heating in winter, ensuring that the pet's living environment is not affected by extreme cold or heat when the owner is home. However, when the owner is not home or turns off the air conditioning to save electricity, the pet will be affected by extreme cold or heat. Currently, some pet beds have heating functions to keep pets warm, suitable for use in cold environments. However, they cannot cool pets in hot environments, thus affecting the usability of the pet bed. Therefore, the functionality of pet beds can be further developed to provide a more comfortable resting environment for pets. Utility Model Content

The energy conduction block and the pet carrier layer form a heat transfer. The bottom cover is provided with an air inlet that communicates with the mounting cavity, and the side of the housing is provided with an air outlet that communicates with the mounting cavity. The fan draws in the air entering the mounting cavity from the air inlet, blows it toward the heat sink, and then discharges it through the air outlet.

[0009] The installation cavity is equipped with a guide structure that draws air in from the air inlet, sucks it in by the fan, and discharges it towards the air outlet.

[0010] The pet kennel also includes a control device that is electrically connected to the control circuit board.

The two airflow guiding plates are located on both sides of the heating and cooling components, with the ends of the two airflow guiding plates extending toward the inner wall of the mounting cavity, thus blocking the air outlet in the middle of the inner sides of the two airflow guiding plates.

[0015] The upper edge of the deflector plate is attached to the lower surface of the pet carrier layer, and the lower edge of the deflector plate is attached to the inner surface of the bottom cover, forming a deflection channel between the inner side of the deflector plate, the upper surface of the bottom cover, the inner wall of the mounting cavity, and the lower surface of the pet carrier layer.

[0016] As a further solution, the pet support layer includes a base plate layer, a heat-conducting plate layer, and a panel layer;

[0017] The base plate is fixedly installed inside the housing, forming an open mounting cavity below the base plate. The heat-conducting plate layer and the panel layer are placed on the base plate layer in sequence. Through slots are opened on the base plate layer and the heat-conducting plate layer respectively. The energy-conducting block is located in the slot of the heat-conducting plate layer. The panel layer and the heat sink are connected by a fixing connector.

[0018] As a further embodiment, the control device is a control knob, touch screen, or control button mounted on the outside of the housing and electrically connected to the control circuit board, and a display screen electrically connected to the control circuit board is installed on the housing.

[0019] As a further solution, a sensor probe is installed in the housing shell to detect whether there is a pet on the pet-carrying layer. The sensor probe is electrically connected to the control circuit board.

[0020] As a further solution, a gap-generating structure is provided at the bottom of the nest shell to create a gap between the air inlet and the surface where the pet nest is placed.

[0021] As a further option, a protective plate is installed on the bottom cover, and the protective plate is bent along the height direction of the housing shell towards the outer periphery of the housing shell.

[0023] 1. In this solution, the heating and cooling components can achieve the heating and cooling effects of the pet bed, allowing the pet to enjoy a suitable temperature in different seasons. Especially in the hot summer or cold winter, after the owner goes out and turns off the indoor air conditioning or heating equipment, the pet can still be provided with a comfortable resting place in extreme ambient temperatures.

[0024] 2. By using a flow-guiding structure to accelerate the airflow around the heating and cooling components and constrain the direction of airflow, as well as to better guide the hot air around the heating and cooling components toward the outside of the pet bed, the heat dissipation effect and efficiency are increased, ensuring the stable operation of the heating and cooling components and thus enhancing the stability of the pet bed.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1 Figure 8 The present invention provides the following technical solution:

[0039] A pet bed includes a bed shell 1, which can be round, rectangular, polygonal, or other shapes, and can be made of injection molded parts or metal parts.

[0040] The nest shell 1 has a horizontal pet support layer inside, which is used for the pet to sit and lie down and support the pet. A mat 2 can be placed on the pet support layer to enhance the comfort of the pet sitting and lying down. The perimeter of the nest shell 1 above the pet support layer extends beyond the pet support layer to form a perimeter enclosure of a certain height.

[0041] The nest shell 1 has an open mounting cavity 3 located below the pet support layer. The bottom of the nest shell 1 is detachably fitted with a bottom cover 4 that seals the bottom of the mounting cavity 3. The bottom cover 4 forms a relatively closed space for the mounting cavity 3. The bottom cover 4 can be detachably fitted to the bottom of the nest shell 1 with screws.

[0042] The mounting cavity 3 houses a heating and cooling assembly and a control circuit board 5 electrically connected to the assembly. The control circuit board 5 controls the operating status of the heating and cooling assembly. The heating and cooling assembly includes a thermoelectric semiconductor cooling chip 6, an energy-conducting block 7, a heat sink 8, and a fan 9. The thermoelectric semiconductor cooling chip 6 has heating and cooling functions and uses existing semiconductor cooling chips. The energy-conducting block 7 is used to conduct energy generated by the thermoelectric semiconductor cooling chip 6, accelerating energy diffusion. The heat sink 8 is used because the thermoelectric semiconductor cooling chip 6 cools on one side (low-temperature end) and heats on the other (high-temperature end). If the heat at the high-temperature end is not dissipated in time, it will cause the overall temperature of the equipment to rise, and may even damage components. The heat sink 8 quickly removes the heat from the high-temperature end through heat conduction, ensuring continuous and stable operation of the equipment. The fan 9 is used in conjunction with the thermoelectric semiconductor cooling chip 6 to further accelerate heat diffusion.

[0043] The thermoelectric semiconductor cooling chip 6 is installed in the middle above the heat sink 8, forming a close fit with the heat sink 8. The fan 9 is installed below the heat sink 8 to blow air towards the heat sink 8, carrying away the heat conducted from the heat sink 8. The energy conduction block 7 is installed on the heat sink 8, above the thermoelectric semiconductor cooling chip 6. The close fit between the energy conduction block 7 and the thermoelectric semiconductor cooling chip 6 improves the heat conduction effect. The energy conduction block 7 forms a heat transfer with the pet carrier layer. Through the energy conduction block 7, the energy generated by the thermoelectric semiconductor cooling chip 6 is directed towards the pet carrier layer, so that the pet carrier layer can achieve the effect of heating or cooling.

[0044] The bottom cover 4 is provided with an air inlet 10 that communicates with the mounting cavity 3. The side of the nest shell 1 is provided with an air outlet 11 that communicates with the mounting cavity 3. The fan 9 is located near the air inlet 10. The fan 9 draws in the air entering the mounting cavity 3 from the air inlet 10 and blows it toward the radiator 8 to diffuse the heat. The air is then discharged through the air outlet 11, allowing the heat to diffuse to the outside of the pet nest.

[0045] The mounting cavity 3 is equipped with a flow guide structure that draws in air from the air inlet 10, which is then drawn by the fan 9 and discharged towards the exhaust port 11. This structure accelerates the airflow within the mounting cavity 3, restricts the direction of airflow, and better guides the hot air within the mounting cavity 3 towards the outside of the pet bed, reducing the residence time of the hot air within the mounting cavity 3, thereby increasing the heat dissipation effect and efficiency.

[0046] The pet kennel also includes a control device electrically connected to the control circuit board 5, which adjusts the operating status of the heating and cooling components through the control circuit in the control circuit board 5.

[0047] In one embodiment, a filter assembly is installed on the bottom cover 4 to filter the air entering the mounting cavity 3 from the air inlet 10, thereby preventing dust in the external air from entering the mounting cavity 3 through the air inlet 10. The filter assembly includes a filter element 12 and a filter element perforated cover 13. A constraint perforated plate 14 is fixedly installed inside the air inlet 10. The filter element perforated cover 13 is detachably mounted on the bottom cover 4 to facilitate the cleaning and replacement of the filter element 12. The filter element 12 is mounted between the filter element cover and the perforated constraint plate. The constraint perforated plate 14 limits the upper end of the filter element 12 when it is installed, and the filter element perforated cover 13 limits the lower end of the filter element 12, thereby installing the filter element 12.

[0048] In practical implementation, the air inlet 10 can be designed as a channel with a certain height, so that the filter element 12 is installed inside the channel-shaped air inlet 10, which allows for better assembly of the filter element 12. The housing of the fan 9 covers the air inlet 10, allowing the fan 9 to smoothly draw air from the air inlet 10. The perforations mentioned in the filter element perforation cover 13 and the constraint perforation plate 14 refer to the perforations on each to reduce obstruction of the incoming air and also to provide corresponding limiting for the filter element 12. The shape of the perforations can be designed according to needs, as long as they have through holes to allow air circulation.

[0049] A disassembly and rotation part 15 is fixedly provided in the center of the outer surface of the filter element hollow cover 13. It can be a protruding knob structure that protrudes from the lower surface of the filter element hollow cover 13, or a recessed knob structure that is recessed into the lower surface of the filter element hollow cover 13. As long as the rotational force is applied to the disassembly and rotation part 15, it can drive the filter element hollow cover 13 to rotate. Multiple spaced locking blocks 16 are fixedly provided on the outer periphery of the filter element hollow cover 13. An annular limiting groove 17 is provided on the inner periphery of the air inlet 10 on the bottom cover 4 for the locking blocks 16 to be screwed in. The lower side of the annular limiting groove 17 has a notch for the locking blocks 16 to be engaged. After the filter element hollow cover 13 rotates, the locking blocks 16 rotate into the annular limiting groove, so that the filter element hollow cover 13 is engaged in the air inlet 10 of the bottom cover 4.

[0050] In one embodiment, the airflow guiding structure includes two airflow guiding plates 18 disposed within the mounting cavity 3. The airflow guiding plates 18 are located on both sides of the heating and cooling assembly. The ends of the two airflow guiding plates 18 extend toward the inner wall of the mounting cavity 3, blocking the air outlet in the middle of their inner surfaces. That is, after the ends of the airflow guiding plates 18 extend, they fit against the inner wall of the mounting cavity 3. The end portions of the two airflow guiding plates 18 are located on both sides of the air outlet. In practice, there are two air outlets, located on the sides of the housing 1 on both sides of the heating and cooling assembly. That is, during the heat dissipation process of the fan 9, the air generated by the fan 9 can be discharged toward the air outlets on both sides simultaneously, thereby accelerating the heat dissipation efficiency.

[0051] An exhaust grille 19 is provided inside the exhaust vent 11 to provide shielding and protection for the exhaust vent.

[0052] In one embodiment, the pet carrier layer includes a base plate layer 20, a heat-conducting plate layer 21, and a panel layer 22. The base plate layer 20 is fixedly disposed horizontally inside the nest shell 1. When the nest shell 1 is made of plastic, the base plate layer 20 can be integrally injection molded with the nest shell 1.

[0053] An open mounting cavity 3 is formed below the base plate layer 20. The heat-conducting plate layer 21 and the panel layer 22 are placed on the base plate layer 20 in sequence, that is, the heat-conducting plate layer 21 is placed flat on the upper surface of the base plate layer 20, and the panel layer 22 is placed flat on the upper surface of the heat-conducting plate layer 21. The base plate layer 20 and the heat-conducting plate layer 21 are respectively opened in the middle position to allow the energy-conducting block 7 to be inserted. The energy-conducting block 7 is placed in the slot 23 of the heat-conducting plate layer 21 and is in contact with the heat-conducting plate layer 21 to form heat transfer. Both the heat-conducting plate layer 21 and the panel layer 22 can be made of aluminum plates with good heat transfer capacity to accelerate energy transfer and radiation, thereby enhancing the cooling and heating capacity of the pet nest.

[0054] The panel layer 22 and the heat sink 8 are connected by a screw fastener screwed in from above the panel layer 22, allowing the entire heating and cooling assembly to be installed as a single unit under the pet carrier layer. During assembly and disassembly, after removing the bottom cover 4, the screw fastener is screwed in from above the panel layer 22 to assemble and disassemble the heating and cooling assembly.

[0055] In one embodiment, the upper edge of the guide plate 18 is attached to the lower surface of the base plate layer 20, and the lower edge of the guide plate 18 is attached to the inner surface of the bottom cover 4. This forms a sealed flow channel between the inner side of the guide plate 18, the upper surface of the bottom cover 4, the inner wall of the mounting cavity 3, and the lower surface of the base plate layer 20, thereby enhancing the stability of air exhaust to the outside. The inner side of the guide plate 18 is preferably straight to avoid obstructing airflow.

[0056] In one embodiment, the ends of the two guide vanes 18 near the exhaust port 11 can be designed as constricted openings. This can generate a certain pressure boosting effect at the exhaust port 11 during the exhaust process, accelerate the airflow speed at the exhaust port 11 towards the outside, and have a certain effect on cleaning the exhaust port 11.

[0057] When the base plate layer 20 is a plastic part, the guide plate 18 can be formed with the base plate layer 20 by one injection molding. When the guide plate layer is a metal part, the guide plate 18 can also be fixed to it by welding with a metal part.

[0058] In one embodiment, a gap-generating structure is provided below the pet bed shell 1 to create a gap between the air inlet 10 and the pet bed placement surface. This gap-generating structure is mainly to prevent the pet bed placement surface from obstructing the air inlet 10 and affecting the air entering from the air inlet 10. The gap-generating structure used in this application consists of four support legs 24 installed below the pet bed to support the entire pet bed. The support legs can be installed on the bottom cover 4 or on the pet bed shell 1. Alternatively, they can extend downwards from the corners below the pet bed shell 1 to form feet to support the pet bed. When the support legs of this application are not provided, the pet bed can also be placed on other supports that can support the pet bed, as long as the air inlet 10 is not in contact with the pet bed placement surface and the pet bed can be placed stably.

[0059] In one embodiment, a protective plate 25 is screwed onto the bottom cover 4, and the protective plate 25 bends upward along the height direction of the nest shell 1 towards the outer periphery of the nest shell 1. The protective plate is mainly arranged in the corners below the outer periphery of the pet nest, and can play a certain protective role.

[0060] In one embodiment, the control device is a control knob 26, a touch screen, or control buttons mounted on the outside of the housing 1 and electrically connected to the control circuit board 5. The control device can be used to control the operating mode of the heating and cooling components, such as a winter heating mode and a summer cooling mode. The accompanying drawings show the use of a control knob to control the operating mode of the heating and cooling components. The heating and cooling components in this application can be existing models in the prior art, and the circuitry in the control circuit board 5 is compatible with the corresponding existing heating and cooling components, which will not be elaborated further here.

[0061] A display screen 27, electrically connected to the control circuit board 5, is installed on the housing 1 to display the operating temperature of the heating and cooling components. Mounting holes are provided in the side wall of the housing for mounting the display screen.

[0062] In one embodiment, a sensor 28 for detecting whether a pet is on the pet carrier layer is provided on the pet housing 1. The sensor 28 is electrically connected to the control circuit board 5. The sensor 28 is installed inside the perimeter enclosure above the pet housing 1, facing upwards towards the pet carrier layer to achieve effective detection. When the cooling / heating operation mode is enabled, if the sensor 28 detects no pet above the pet housing, the heating / cooling components go into low-power standby mode. If a pet is detected, the heating / cooling components return to the set operating mode.

[0063] In one embodiment, the control circuit board 5 is electrically connected to an external power source or a built-in power source located in the pet housing 1. When an external power source is used, a power plug 29, which is electrically connected to the control circuit board 5, is connected to a socket to power all electronic components in the pet housing. Alternatively, a built-in power source can be used, which may be a rechargeable energy storage battery. This energy storage battery can be installed with the control circuit board 5 in the space between the outer side of the guide plate 18 and the inner wall of the mounting cavity 3, thus separating it from the heating and cooling components.

[0064] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
