Description

Technical Field

[0001] This invention patent is in the field of livestock breeding technology, specifically relating to a calf heating jacket for use in low-temperature environments. Background Technology

[0002] In calf island rearing, controlling the temperature of the calf's living environment in winter is difficult. Newborn calves' thermoregulation abilities are not fully developed, and low temperatures can negatively impact their health and growth. Analysis of existing calf jackets on the market reveals that almost all products currently use imitation silk cotton or down cotton as filling to ensure the calf's health and growth in low winter conditions. However, these common calf insulation jackets still have shortcomings: existing calf jackets are often thermally insulating garments, generating and blocking heat through the filling. However, calves can only generate a limited amount of heat, and calf jackets require frequent washing, causing their insulation effectiveness to gradually decrease with each wash. This can easily lead to insufficient insulation and hinder the calf's healthy growth and development. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a calf heating jacket that solves the problems of decreased insulation capacity and insufficient insulation effect of existing calf jackets with repeated washing. Through active heating and precise temperature control, the invention ensures the healthy growth of calves in low-temperature environments.

[0004] This invention provides a calf heating jacket for low-temperature environments, comprising a jacket body, neck straps fixedly connected to both sides of one end of the jacket body, and groin protectors fixedly connected to both sides of the jacket body. Carbon fiber heating element modules are disposed inside the neck straps, jacket body, and groin protectors. A hook assembly is disposed on one side of one groin protector, and a connecting hook groove is disposed on one side of the other groin protector. Four hoof sleeves are disposed on the outer side of the jacket body. A rechargeable power supply mechanism is fixedly installed at one end of the surface of the jacket body. A flexible thermistor sensor for the spine is installed in the middle of the inner wall of the jacket body. Flexible thermistor sensors for the neck are fixedly installed on the inner sides of both neck straps. Flexible thermistor sensors for the abdomen are fixedly installed on both sides of the inner wall of the jacket body. A flexible photovoltaic panel is disposed in the middle of the outer side of the jacket body. A connecting plug is disposed on one side of the flexible photovoltaic panel. A charging port assembly is fixedly installed on the surface of one side of the rechargeable power supply mechanism.

[0005] Preferably, the hook assembly includes an elastic fastening band, which is disposed on the groin protector. One end of the elastic fastening band is fixedly connected to a connecting hook, which engages with a connecting hook groove block, thereby securing the calf jacket and providing warmth to the groin area.

[0006] Preferably, one end of each of the four hoof protectors is fixedly connected to an elastic foot, and the other end of two of the hoof protectors is fixedly connected to a first elastic band, while the other end of the other two hoof protectors is fixedly connected to a second elastic band. One end of each of the two first elastic bands is fixedly fitted with a locking head, and one end of each of the two second elastic bands is fixedly connected to a locking buckle. The inside of the locking buckle engages with the surface of the locking head, which is beneficial for keeping the hoof warm and makes it easy to wear.

[0007] Preferably, the jacket body includes a nylon tensile outer layer, one side of which is provided with a waterproof layer, one of the neck straps is provided with a first Velcro closure on one side, and the other neck strap is provided with a second Velcro closure on one side, which helps to enhance the service life of the calf jacket.

[0008] Preferably, the rechargeable power supply mechanism includes an electrical control box, which is mounted on the jacket body. A lithium polymer battery module is fixedly installed on one side of the inner wall of the electrical control box, and a power supply port is fixedly installed on the other side of the inner wall of the electrical control box. A module assembly is provided in the middle of the inner wall of the electrical control box, and a switch assembly is installed on the surface of the electrical control box. A protective assembly for protecting the inside of the electrical control box is fixedly installed at one end of the electrical control box, which can continuously provide energy to the heating module.

[0009] Preferably, the switch assembly includes a waterproof switch plate, which is mounted on the electrical control box. An indicator light is provided on one side of the surface of the waterproof switch plate, which can control the working status of the heating module and indicate whether the battery has power.

[0010] Preferably, a connection terminal is fixedly installed at one end of the surface of the lithium polymer battery module, and the connection terminal is plugged into the power supply port.

[0011] Preferably, the module assembly includes a controller module and an adjustment module, which are electrically connected. The controller module is electrically connected to the lithium polymer battery module through a waterproof switch board, which is beneficial for controlling the heating module and keeping the calf's body temperature within a suitable range.

[0012] Preferably, the protective assembly includes a connecting cover plate, which is fixedly connected to the control box by bolts. A sealing gasket is provided between the control box and the connecting cover plate. The surface of the connecting cover plate has multiple first heat dissipation grooves. A connecting shield is fixedly connected to one side of the connecting cover plate. A strong magnetic ring is provided at the connection between the connecting shield and the connecting cover plate. Second heat dissipation grooves are provided on both sides of the connecting shield. A metal sheet is provided on the inner wall of the connecting shield. A sealing plate is slidably connected inside the connecting shield. A push-pull rod is fixedly connected to one side of the sealing plate. A handle block is fixedly connected to one end of the push-pull rod. A silicone rubber ring is provided on the other side of the sealing plate. Connecting magnetic sheets are provided on both sides of the connection between the sealing plate and the push-pull rod. A strong sealing magnet is provided inside the silicone rubber ring, which is beneficial for providing battery heat dissipation while also providing a good seal when the calf jacket needs to be cleaned.

[0013] Preferably, the charging port assembly includes a protective box, which is mounted on the control box. A connection port is fixedly installed on the top of the inner wall of the protective box, and a card holder is fixedly connected to one side of the protective box. A threaded protective sleeve is engaged inside the card holder.

[0014] Preferably, the flexible photovoltaic panel is connected to the jacket body via Velcro.

[0015] The present invention has the following technical effects: 1. A carbon fiber heating module is added to the inside of a traditional down or imitation silk cotton-filled calf jacket. This heating module is added to the areas where the calf needs special protection. The calf jacket is also equipped with a flexible photovoltaic panel and a battery. It provides the calf with the required heat through self-heating. The temperature of the heating module can be adjusted through sensors and control modules to keep the calf's body temperature within a suitable range, which is conducive to the healthy growth and development of the calf.

[0016] 2. The calf jacket is made of nylon tensile and waterproof material, which can prevent damage to the internal heating module when washing. It uses flexible photovoltaic panels to generate electricity to power the heating module, saving costs and being environmentally friendly.

[0017] 3. An electrical control box is installed on the calf jacket, housing the battery and control module. A protective component is installed at the seal of the control box. During normal use, pulling the push-pull rod to one side moves the sealing plate away from the first heat dissipation slot and is held in place by a connecting magnetic sheet and a metal plate. At this time, the first and second heat dissipation vents are connected, allowing for natural heat dissipation from the low external environment. When the calf jacket needs to be washed, pressing the push-pull rod downwards causes the strong sealing magnet inside the silicone rubber ring on the sealing plate to attract the strong magnetic ring, sandwiching a layer of silicone rubber in the middle to form a good seal. This protects the internal electronic components during washing. The operation is simple and practical. Attached Figure Description

[0020] To make the objectives, advantages and features of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figure 1-10 This invention provides a calf insulation jacket, comprising a jacket body 1, with neck straps 3 fixedly connected to both sides of one end of the jacket body 1, and groin protectors 18 fixedly connected to both sides of the jacket body 1. Carbon fiber heating element modules 11 are provided inside the neck straps 3, jacket body 1, and groin protectors 18. A hook assembly is provided on one side of one groin protector 18, and a connecting hook groove block 21 is provided on one side of the other groin protector 18. Four hoof sleeves 12 are provided on the outer side of the jacket body 1. A rechargeable power supply mechanism is fixedly installed at one end of the surface of the jacket body 1. A flexible thermistor sensor 7 is installed in the middle of the inner wall of the jacket body 1. Flexible thermistor sensors 8 are fixedly installed on the inner sides of both neck straps 3. Flexible thermistor sensors 9 are fixedly installed on both sides of the inner wall of the jacket body 1. A flexible photovoltaic panel 41 is provided in the middle of the outer side of the jacket body 1. A connecting plug 44 is provided on one side of the flexible photovoltaic panel 41. A charging port assembly is fixedly installed on the surface of one side of the rechargeable power supply mechanism.

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4Furthermore, the hook assembly includes an elastic fastening band 19, which is disposed on the groin protector 18. One end of the elastic fastening band 19 is fixedly connected to a connecting hook 20, which engages with the connecting hook groove block 21. One end of each of the four hoof sleeves 12 is fixedly connected to an elastic foot 13. The other end of two of the hoof sleeves 12 is fixedly connected to a first elastic band 14, and the other end of the other two hoof sleeves 12 is fixedly connected to a second elastic band 15. One end of each of the two first elastic bands 14 is fixedly installed with a snap-lock head 16, and one end of each of the two second elastic bands 15 is fixedly connected to a snap-lock buckle 17. The inside of the snap-lock buckle 17 engages with the surface of the snap-lock head 16. The jacket body 1 includes a nylon tensile outer layer 4, a waterproof layer 2 is provided on one side of the nylon tensile outer layer 4, a first Velcro 5 is provided on one side of one of the neck straps 3, and a second Velcro 6 is provided on one side of the other neck strap 3. In use, the jacket body 1 is draped over the calf, and the neck strap 3 is wrapped around the calf's neck. The first Velcro 5 and the second Velcro 6 are then fastened together to provide good fixation and insulation. The elastic fastening strap 19 is wrapped around the two abdominal groin protectors 18, and the connecting hook 20 on the elastic fastening strap 19 is hooked onto the connecting hook groove block 21 to keep the calf's abdominal groin warm. Then, the first elastic strap 14 and the second elastic strap 15 are pulled up to the calf's spine, and the locking head 16 and the locking buckle 17 are snapped together. The locking head 16 and the locking buckle 17 are existing technologies. The buckles and four hoof sleeves 12 are the same. The elastic bands and buckles on the two hoof sleeves 12 on the same side are the same. The hoof sleeves 12 are worn separately and are very easy to put on and take off. The elastic leg straps 13 can adapt to hooves of different diameters and can provide good fixation while ensuring a certain degree of comfort. The surface material of the jacket body 1 is composed of a nylon tensile outer layer 4 and a waterproof layer 2. It can provide strong tensile strength and good waterproof performance, and can also protect the down or imitation silk cotton inside as much as possible, reducing the loss of warmth after washing.

[0023] See Figure 4 , Figure 5 , Figure 9 and Figure 10Furthermore, the rechargeable power supply mechanism includes an electronic control box 23, which is mounted on the jacket body 1. A lithium polymer battery module 25 is fixedly installed on one side of the inner wall of the electronic control box 23, and a power supply port 24 is fixedly installed on the other side of the inner wall of the electronic control box 23. A module assembly is provided in the middle of the inner wall of the electronic control box 23, and a switch assembly is installed on the surface of the electronic control box 23. A protective assembly for protecting the interior of the electronic control box 23 is fixedly installed at one end of the electronic control box 23. The switch assembly includes a waterproof switch plate 39, which is mounted on the electronic control box 23. An indicator light 40 is provided on one side of the surface of the waterproof switch plate 39. A connection terminal 26 is fixedly installed on one end of the surface of the lithium polymer battery module 25. The connection terminal 26 is plugged into the power supply port 24. The module assembly includes a controller module 27 and an adjustment module 28. The controller module 27 and the adjustment module 28 are electrically connected. The controller module 27 is electrically connected to the lithium polymer battery module 25 through a waterproof switch plate 39. The charging port assembly includes a protective box 42. The protective box 42 is installed on the electronic control box 23. A connection port 43 is fixedly installed on the top of the inner wall of the protective box 42. A card holder 45 is fixedly connected to one side of the protective box 42. A threaded protective sleeve 46 is snapped into the inside of the card holder 45. In use, carbon fiber heating element modules 11 are laid on the jacket body 1, neck brace 3, and groin protector 18. Flexible thermistor sensors located throughout the calf jacket are waterproofed to meet normal cleaning and usage requirements. The sensors and heating mechanism inside the calf jacket are integrated into the power supply port 24 inside the electrical control box 23. Each flexible thermistor sensor is electrically connected to the controller module 27, which is electrically connected to the adjustment module 28. The adjustment module 28 is connected to the carbon fiber heating elements inside the neck brace 3, jacket body 1, and groin protector 18. The heating element module 11 is electrically connected, and the indicator light 40 is electrically connected to the lithium polymer battery module 25 via the waterproof switch plate 39. If the battery is depleted, the indicator light 40 will turn off, serving as an alert. The lithium polymer battery module 25 is connected to the power supply port 24 via the connector 26 to power all the electronic components inside the calf jacket. Flexible thermistor sensors at various locations can detect the temperature of the calf's spine, neck, and abdomen. The sensors transmit the detected temperatures to the controller module 27, which sets the temperature range. Module 27 sends instructions to adjustment module 28, which in turn adjusts the output power of carbon fiber heating element module 11 to stabilize the calf's body temperature at 13-15 degrees Celsius, which is beneficial to the calf's growth and development. When the calf is active, the flexible photovoltaic panel 41 on the jacket converts solar energy into electrical energy. Connecting plug 44 and connecting socket 43 are plugged in. Connecting socket 43 is electrically connected to the lithium polymer battery module 25 and is actually the battery's charging port. Originally, the photovoltaic panel had a battery, but its storage capacity is generally small; therefore, the connecting plug 44 and connecting socket 43 are used to charge the rotating ring. Electrical energy is stored in the lithium polymer battery module 25, which is similar to the principle of existing photovoltaic panels, except that the energy is stored in a larger battery. One side of the protective box 42 is transparent, which makes it easy to plug in the plug. At the same time, it can prevent the plug and socket from being damaged in the rain. When it is necessary to wash the jacket body 1, the flexible photovoltaic panel 41 can be removed. The flexible photovoltaic panel 41 is connected by Velcro. It can be cleaned by unplugging the connector 44. The outer side of the connector 43 is provided with a threaded layer. Before cleaning, the threaded sleeve 46 can be screwed on the threaded layer to prevent water from entering the connector 43.

[0024] See Figure 6 , Figure 7 and Figure 8Furthermore, the protective component includes a connecting cover plate 30, which is fixedly connected to the electrical control box 23 by bolts. A sealing gasket 29 is provided between the electrical control box 23 and the connecting cover plate 30. Multiple first heat dissipation grooves 31 are formed on the surface of the connecting cover plate 30. A connecting shield 32 is fixedly connected to one side of the connecting cover plate 30. A strong magnetic ring 34 is provided at the connection between the connecting shield 32 and the connecting cover plate 30. Second heat dissipation grooves 33 are formed on both sides of the connecting shield 32. A metal sheet is provided on the inner wall of the connecting shield 32. A sealing plate 35 is slidably connected inside the connecting shield 32. A push-pull rod 38 is fixedly connected to one side of the sealing plate 35. A handle block 22 is fixedly connected to one end of the push-pull rod 38. A silicone rubber ring 36 is provided on the other side of the sealing plate 35. Connecting magnetic sheets 10 are provided on both sides of the connection between the sealing plate 35 and the push-pull rod 38. A strong sealing magnet 37 is provided inside the silicone rubber ring 36. In use, the connecting cover 30 is fixedly connected to the control box 23 with screws, and a sealing gasket 29 is provided at the connection point to achieve a good sealing effect. When the calf is wearing and using the device normally, the handle block 22 is squeezed to pull the push-pull rod 38 to the side away from the first heat dissipation slot 31. At this time, the sealing plate 35 is away from the first heat dissipation slot 31 and is attracted to the metal plate on the connecting cover 32 by the connecting magnet 10. At this time, the sealing plate 35 is fixed, and the first heat dissipation slot 31 and the second heat dissipation slot 33 are connected to the outside world, which can dissipate heat from the low temperature environment of the outside world, so that the battery can be used stably. When the cow jacket needs cleaning, we take off the cow jacket and press the handle block 22 to move the sealing plate 35 toward the first heat dissipation groove 31. At this time, the strong sealing magnet 37 inside the silicone rubber ring 36 is tightly attracted to the strong magnet ring 34, so that one layer of the silicone rubber ring 36 is sandwiched between the two magnet rings, which can form a good sealing effect. It can be cleaned directly through the water pipe and can effectively protect the components inside the electrical control box 23. When using, we pull the connection between the strong sealing magnet 37 and the strong magnet ring 34 to make the connecting magnetic sheet 10 and the metal sheet attract again, so that heat dissipation can be normal.

[0025] In this embodiment, the silicone rubber material provides good waterproofing and is widely used in various fields. The waterproof switch plate 39 controls the opening and closing of the entire temperature control and heating mechanism. When the waterproof switch plate 39 is on, the indicator light 40 illuminates; when the waterproof switch plate 39 is off, the indicator light 40 turns off. The indicator light 40 also turns off when the battery is depleted, alerting the livestock handlers. The carbon fiber heating element module 11 itself is also waterproofed to a certain extent, meeting normal usage requirements. The flexible photovoltaic panel 41 is mainly installed on the calf's back, offering high solar energy conversion efficiency. Furthermore, its Velcro connection reduces the risk of damage when the calf enters the shed. Wear on the surface of photovoltaic panel 41 is caused by the small space inside the breeding shed, where calves easily get close and rub against each other, which can easily damage the flexible photovoltaic panel 41. It should be noted that this invention is a calf insulation jacket, and all components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
