Description

Technical Field

[0001] The present application relates to the technical field of outdoor tents, and in particular to a thermal drive module and a ventilated and breathable outdoor tent. Background Art

[0002] Outdoor tents are essential equipment for outdoor activities, used to provide temporary accommodation and protection. Tent fabrics are usually made of waterproof, breathable, and wear-resistant materials such as nylon and polyester, and the breathability of the tent is very important for maintaining internal air circulation and comfort. However, most tents on the market currently use passive ventilation, that is, a certain amount of air circulation is maintained through the gauze curtains set on the tent, which is far less effective than active ventilation and cannot meet the diverse needs of outdoor enthusiasts.

[0003] In the related art, a Chinese patent with application number CN202410782545.6 proposes a ventilated and breathable tent, which includes a tent frame and a tent body laid on the tent frame; openings are provided on both sides of the tent body, fixed frames are fixed at the openings, and a ventilated and breathable device is detachably mounted on the fixed frame. The ventilated and breathable device includes a mounting plate detachably arranged on the fixed frame, and a plurality of ventilated and breathable units detachably arranged on the mounting plate. The ventilated and breathable units are suitable for forward or reverse mounting on the mounting plate. When the ventilated and breathable units are forward mounted, the ventilated and breathable units guide the external airflow into the tent body, and when the ventilated and breathable units are reversely mounted, the ventilated and breathable units guide the air in the tent body to the outside. By installing the ventilated and breathable units in the forward and reverse directions, the exchange of airflow inside the tent body and the effect of blowing air to the human body inside the tent can be achieved.

[0004] The above-mentioned related technologies have the following defects: the ventilation unit needs to rely on an external independent power supply to work, which will increase the weight of the materials carried by the user too much on the one hand, and once the independent power supply is exhausted, the ventilation unit cannot maintain normal operation and cannot meet the ventilation requirements for a long time. Therefore, there are still many limitations in its use. Summary of the invention

[0005] In order to improve the problem that the ventilation unit on the existing outdoor tent is difficult to operate for a long time due to the limitation of the external power supply, the present application provides a thermal drive module and a ventilation outdoor tent.

[0006] A thermal drive module provided in the first aspect of the present application adopts the following technical solution: A thermal drive module, comprising: A plurality of heat collecting tubes are arranged side by side and filled with a fluid medium; A pressure relief pipe connected to the top of the heat collecting pipe; A power tank, wherein a rotating shaft is rotatably mounted inside the power tank, one end of the rotating shaft extends out of the bottom end of the power tank, and the other end is circumferentially fixed with a plurality of blades, and one end of the pressure relief pipe away from the heat collecting pipe is tangentially connected to the power tank, and the output end of the pressure relief pipe points to the blades; and A capillary tube, one end of which is connected to the bottom of the power tank and the other end of which extends from the bottom of the heat collecting tube to the inside of the heat collecting tube, wherein the length of the capillary tube in the heat collecting tube is greater than the liquid level of the fluid medium in the heat collecting tube in the initial state; A fan is installed at one end of the rotating shaft extending out of the power tank, and a ventilation duct system is connected to the fan output end.

[0007] Furthermore, a buffer tank is connected to the bottom end of the power tank, the capillary tube is connected to the buffer tank, and the blades push the medium in the power tank to flow into the buffer tank when rotating under the impact of the medium sprayed from the pressure relief pipe.

[0008] Furthermore, the pressure relief pipe is configured as a high temperature resistant coiled pipe, the outer peripheral wall of the power tank is connected to a plurality of quick connectors distributed in a circular array with equal spacing in its axial direction, and the pressure relief pipe is connected to the power tank through the quick connector; The plurality of quick connectors distributed along the axial direction of the power tank are arranged in a staggered manner.

[0009] Furthermore, both ends of the central axis of the fan are fixedly connected with a sleeve detachably connected to the rotating shaft, and the rotating shaft and the sleeve are arranged to move together; When ventilation is required, the sleeve at one end of the fan is connected to the rotating shaft, so that the fan can enter a ventilation state with the help of the ventilation duct system when rotating; When it is necessary to deliver warm air, the sleeve at the other end of the fan is connected to the rotating shaft so that when the fan rotates, the hot air near the power tank is delivered through the ventilation duct system to enter the air supply state.

[0010] The second aspect of the present application provides a ventilated and breathable outdoor tent, which adopts the following technical solution: A ventilated and breathable outdoor tent comprises a tent frame and a tent body. At least two oppositely arranged thermal drive modules as described above are arranged on one side of the tent body.

[0011] Furthermore, the ventilation duct system comprises: A main air duct is arranged along the tent frame and passes through the tent body, one end of which extends to the outside of the tent body and connects with the fan, and the other end of which extends into the tent body; An adjusting rope, one end of which is arranged at the bottom end of the main air duct; An adjusting buckle is arranged in the tent body and is higher than the bottom end of the main air duct, and is used to cooperate with the adjusting rope to adjust the opening direction of the bottom end of the main air duct.

[0012] Furthermore, the main air duct is made of two layers of airtight fabric and has a cylindrical shape with an inflation cavity in the tube wall. An air nozzle for inflating the inflation cavity is provided on the outer wall of the main air duct. The upper part of the main air duct is sewn and fixed to the inner wall of the tent body, and the lower part connected to the adjustment rope is freely set.

[0013] Furthermore, one end of the main air duct connected to the adjustment rope is provided with a restraining piece for adjusting the diameter of the main air duct outlet.

[0014] Furthermore, one end of the main air duct extending outside the tent body is connected with a connecting sleeve, the fan housing is embedded in the connecting sleeve, and one connecting sleeve corresponds to a plurality of main air ducts.

[0015] Furthermore, a mounting frame is overlapped on one side of the tent body, and the thermal drive module and the connecting sleeve are both installed on the mounting frame.

[0016] In summary, the beneficial technical effects of this application are: 1. After the outdoor tent of the present application is built, the mounting frame is overlapped on one side of the tent body. At this time, the multiple heat collecting tubes arranged obliquely on the mounting frame absorb solar energy, which can quickly heat the fluid medium in the heat collecting tube. After being heated, the fluid medium is heated and vaporized into water vapor, which flows from the pressure relief pipe to the power tank and impacts the blades on the rotating shaft with a certain kinetic energy; thus, under the action of the multiple heat collecting tubes, the water vapor with kinetic energy sprayed from the multiple pressure relief pipes impacts the blades corresponding to the rotating shaft, which can drive the rotating shaft to rotate, and then drive the fan blades at the lower end of the rotating shaft to rotate. The fan blades can form airflow when rotating, and actively circulate the air in the tent body with the external air through the ventilation duct system, which can greatly promote the ventilation and air permeability effect of the outdoor tent of the present application; 2. After the water vapor impacts the blades, it is liquefied in the power tank. The internal pressure of the power tank increases during the process of being filled with water vapor, so that the liquefied clean water flows back to the heat collecting tube through the capillary tube, and the siphon effect of the capillary tube can also promote the liquefied clean water to flow back to the heat collecting tube; after absorbing solar energy, the heat collecting tube continues to heat the clean water flowing back in the heat collecting tube, and generates water vapor again. In this cycle, a continuous flow of water vapor impacts the blades in the power tank, so that the fan blades keep rotating continuously, thereby ensuring the continuous ventilation and air permeability of the outdoor tent of the present application, especially during the day when solar energy is sufficient, the thermal drive module of the present application can maintain continuous and stable operation without the help of an external power supply; 3. The outdoor tent of the present application can be ventilated outward or warm air can be delivered inward only by flipping the fan. The heat energy released by the vaporization of water vapor in the power tank and the buffer tank is fully utilized. The tent can be ventilated and heated by wind, which greatly improves the comfort of the outdoor tent of the present application when in use. 4. The setting of the buffer tank connected to the bottom of the power tank can not only prevent the vaporized clean water from accumulating in the power tank and causing great interference to the rotation of the shaft and blades, but also the setting of its heat-conducting material can promote the vaporization process of water vapor in the power tank and the buffer tank; at the same time, when the fan transports hot air to the main air duct, it can also ensure that sufficient heat enters the main air duct with the airflow.

[0026] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0027] The present application embodiment discloses a thermal drive module. Figure 1 , Figure 2 and Figure 3 , the thermal drive module includes: The mounting frame 62 can be folded for storage and used for carrying when unfolded.

[0028] The heat collecting tubes 2 are arranged in multiple numbers side by side and fixedly connected to one side of the mounting frame 62. The interior of the heat collecting tubes 2 is filled with a fluid medium, which may be air or water. In this embodiment, it is set to be clean water, and the fluid medium does not completely fill the heat collecting tubes 2, and generally does not exceed half of the volume of the heat collecting tubes 2.

[0029] The pressure relief pipe 21 is connected to the top of the heat collecting pipe 2 .

[0030] The power tank 3 has a rotating shaft 31 installed therein, which is coaxially arranged with the power tank 3. One end of the rotating shaft 31 extends out of the bottom end of the power tank 3, and the other end is circumferentially fixed with a plurality of blades 32 located in the power tank 3. The end of the pressure relief pipe 21 away from the heat collecting pipe 2 is tangentially connected to the power tank 3, and the output end of the pressure relief pipe 21 points to the blades 32. And The capillary tube 22 has one end connected to the bottom of the power tank 3 and the other end extending from the bottom of the heat collecting tube 2 to the inside of the heat collecting tube 2. The length of the capillary tube 22 extending upward in the heat collecting tube 2 is greater than the liquid level height of the fluid medium in the heat collecting tube 2 in the initial state. If necessary, a one-way valve can also be connected to the top of the capillary tube 2 to prevent the fluid medium in the power tank 3 from reversely entering the capillary tube 22.

[0031] A fan 33 is installed at one end of the rotating shaft 31 extending out of the power tank 3. The blades of the fan 33 are movably connected to the rotating shaft 31, and the wind output end of the fan 33 is connected to a ventilation duct system.

[0032] Therefore, after the mounting frame 62 of the present application is overlapped outdoors, the multiple heat collecting tubes 2 obliquely arranged on the mounting frame 62 absorb solar energy, which can quickly heat the fluid medium in the heat collecting tube 2. After the fluid medium is heated, it heats up and vaporizes, which increases the pressure in the heat collecting tube 2, and then the vaporized water vapor flows from the pressure relief pipe 21 to the power tank 3, and impacts the blades 32 on the rotating shaft 31 with a certain kinetic energy; thus, under the action of the multiple heat collecting tubes 2, the multiple pressure relief pipes 21 spray water vapor with kinetic energy to impact the blades 32 corresponding to the rotating shaft 31, which can drive the rotating shaft 31 to rotate, and then drive the blades of the fan 33 at the lower end of the rotating shaft 31 to rotate, and the blades of the fan 33 can form airflow when rotating, and form active circulation through the ventilation duct system, which can greatly promote the ventilation and air permeability effect of the equipment.

[0033] In this process, water vapor is liquefied in the power tank 3 after impacting the blades 32, and the internal pressure of the power tank 3 increases in the process of being filled with water vapor, so that the liquefied clean water flows back to the heat collecting tube 2 through the capillary 22, and the siphon effect of the capillary 22 can also promote the liquefied clean water to flow back to the heat collecting tube 2; after absorbing solar energy, the heat collecting tube 2 continues to heat the clean water flowing back in the heat collecting tube 2 to generate water vapor again. Such a cycle can form a continuous flow of water vapor impacting the blades 32 in the power tank 3, so that the blades of the fan 33 keep rotating, thereby ensuring the continuous ventilation effect of the present application, especially during the day when solar energy is sufficient, the thermal drive module of the present application can maintain continuous and stable operation.

[0034] Moreover, the thermal drive module is conveniently installed through a detachable and foldable mounting frame 62, and can be conveniently disassembled when not in use; at the same time, the diameter of the heat collecting tube 2 can be selected from 10mm to 50mm according to actual conditions, so as to meet the requirements of convenient carrying and provide sufficient kinetic energy for the fan 33.

[0035] Specifically, refer to Figure 2 , Figure 3 and Figure 4 In order to prevent the vaporized clean water from being stored in the power tank 3 and causing great interference to the rotation of the rotating shaft 31 and the blades 32, the bottom of the power tank 3 is connected to a buffer tank 34, the outer diameter of the buffer tank 34 is smaller than the outer diameter of the power tank 3, and the connection between the two is smoothly transitioned, the capillary 22 is connected to the bottom of the buffer tank 34, and the blades 32 rotate under the impact of the medium ejected from the pressure relief pipe 21, pushing the medium in the power tank 3 to flow into the buffer tank 34. In order to promote the vaporization process of water vapor in the power tank 3 and the buffer tank 34, the buffer tank 34 and / or the power tank 3 can be made of heat-conductive materials, for example, the buffer tank 34 can be set as an aluminum tank or a copper tank.

[0036] And, refer to Figure 2 and Figure 5The pressure relief pipe 21 is configured as a high-temperature resistant coil to maintain the impact kinetic energy of the water vapor in the pressure relief pipe 21. The outer peripheral wall of the power tank 3 is connected to a plurality of quick connectors 35 distributed in a circular array with equal spacing along its axial direction. The pressure relief pipe 21 is connected to the power tank 3 through the quick connectors 35; the plurality of quick connectors 35 distributed along the axial direction of the power tank 3 are staggered so that the water vapor ejected from the plurality of pressure relief pipes 21 forms a multi-angle and multi-faceted continuous impact on the plurality of blades 32 on the rotating shaft 31, so as to ensure the continuity and rotation speed of the rotating shaft 31.

[0037] In this way, after the water vapor in the pressure relief pipe 21 impacts the blades 32 in the power tank 3, it converges into the buffer tank 34 under its own gravity and the thrust of the rotation of the blades 32. The buffer tank 34 with good thermal conductivity promotes the complete vaporization of these water vapor droplets and releases a large amount of heat. The clean water stored in the buffer tank 34 then flows back to the multiple heat collecting tubes 2 through multiple capillaries 22, completing the circulation process.

[0038] In view of this, refer to Figure 2 and Figure 3 , the present application is further configured as follows: both ends of the fan blade axis of the fan 33 are fixedly connected with a sleeve 4 that is detachably connected to the rotating shaft 31, and the rotating shaft 31 and the sleeve 4 are arranged to move together. Specifically, a square hole is opened in the middle of the sleeve 4, and the end of the rotating shaft 31 is fixedly connected with a square shaft that is magnetically attracted in the square hole, or the rotating shaft 31 is threadedly connected to the sleeve 4 to realize the detachable installation of the rotating shaft 31 and the fan 33 on both sides. In this embodiment, threaded holes are opened at both ends of the sleeve 4, and the end of the rotating shaft 31 is fixedly connected with bolts that are threadedly adapted to the threaded holes.

[0039] In this way, after the thermal drive module of the present application is connected to a device that requires ventilation, such as an outdoor tent.

[0040] When ventilation is needed, such as in summer or when there is an odor in the outdoor tent that needs to be removed, the sleeve 4 at one end of the fan 33 is connected to the rotating shaft 31, so that when the fan 33 rotates, the air in the outdoor tent is extracted with the help of the ventilation duct system to enter the exhaust state, which can reduce the air pressure in the outdoor tent and allow fresh air from the outside to enter the outdoor tent from the doors and windows set on the outdoor tent, completing the ventilation process.

[0041] When warm air needs to be delivered, such as in winter or when the outdoor temperature is low, the fan 33 is flipped so that the sleeve 4 at the other end is connected to the rotating shaft 31, so that when the fan 33 rotates, the hot air near the power tank 3 is delivered to the outdoor tent through the ventilation duct system to enter the air supply state, which can not only complete the ventilation process but also increase the temperature inside the outdoor tent.

[0042] Therefore, only by flipping the fan 33 and installing it, the application can achieve the effect of exhausting air outward from the outdoor tent or delivering warm air inward, making full use of the heat energy released by the vaporization of water vapor in the power tank 3 and the buffer tank 34, which can be ventilated and heated, greatly improving the comfort of the application when used in conjunction with an outdoor tent.

[0043] The present application also discloses a ventilated and breathable outdoor tent. Figure 1 and Figure 2 It includes a tent frame 11 and a tent body 12. At least two oppositely arranged thermal drive modules as described above are mounted on a mounting frame 62 on one side of the tent body 12. In this embodiment, the tent frame 11 is a four-main-frame arrangement. The thermal drive module is mounted on a foldable and spliced ​​mounting frame 62. Two thermal drive modules are arranged and are oppositely and obliquely overlapped on the mounting frame 62 to ensure the stability of the thermal drive module on the mounting frame 62.

[0044] In addition, to adapt to the foldable properties of outdoor tents, refer to Figure 6 and Figure 7 , the above ventilation duct system comprises: The main air duct 51 is arranged along the tent frame 11 and penetrates the tent body 12, one end of which extends to the outside of the tent body 12 and connects with the fan 33, and the other end extends into the tent body 12. For example, the tent frame 11 of this embodiment is arranged with four main frames, and the mounting frame 62 is placed on one side of the tent body 12. Then, two main air ducts 51 are arranged on the side of the tent body 12 close to the mounting frame 62 and are respectively attached to the two sewn edges of the tent body 12; An adjusting rope 52, one end of which is arranged at the bottom end of the main air duct 51, which can be fixed or connected via a lifting ring; The adjusting buckle 53 is arranged in the tent body 12 and is higher than the bottom end of the main air duct 51. It is used to cooperate with the adjusting rope 52 to adjust the opening direction of the bottom end of the main air duct 51. Specifically, parts of the adjusting rope 52 of different lengths are fastened to the adjusting buckle 53, so that the direction of the bottom end of the main air duct 51 can be flexibly adjusted.

[0045] Among them, the main air duct 51 is made of two layers of airtight fabrics and has a cylindrical shape with an inflation cavity 511 on the tube wall. An air nozzle 512 for inflating the inflation cavity 511 is provided on the outer wall of the main air duct 51. The upper part of the main air duct 51 is sewn and fixed to the inner wall of the tent body 12, and the lower part connected to the adjustment rope 52 is freely set.

[0046] In addition, one end of the main air duct 51 connected to the adjustment rope 52 is provided with a restraining piece 54 for adjusting the outlet diameter of the main air duct 51. The restraining piece 54 can be a Velcro or a binding rope, thereby changing the air intake and outlet volumes of different main air ducts 51 to facilitate flexible adjustment by the user.

[0047] One end of the main air duct 51 extending outside the tent body 12 is connected to a connecting sleeve 61, and the fan 33 casing is embedded in the connecting sleeve 61. One connecting sleeve 61 corresponds to one or more main air ducts 51. In the present embodiment, one connecting sleeve 61 corresponds to one main air duct 51. The side wall of the connecting sleeve 61 is obliquely connected to a connecting tube 611. The free end of the connecting tube 611 is fixedly connected to a limiting ring 612. The main air duct 51 is sleeved on the connecting tube 611 and is fastened with an elastic rope or Velcro at the position crossing the limiting ring 612. The limiting ring 612 can play an anti-slip and sealing role.

[0048] Thus, after the tent frame 11 props up the tent body 12, the air is inflated into the inflation cavity 511 of the main air duct 51 through the air nozzle 512, so that the main air duct 51 is in a complete and stiff cylindrical shape, and then the end of the main air duct 51 extending outside the tent body 12 is connected and fixed to the connecting tube 611 on the connecting sleeve 61, so that when the thermal drive module is working, the main air duct 51 can form an air guide channel to achieve active ventilation and air permeability between the tent body 12 and the outdoor air. And in actual use, according to the needs of the user, the part of the main air duct 51 that is not connected to the tent body 12 can be pulled by the adjustment rope 52 so that the bottom end of the main air duct 51 is aligned with the target area for directional extraction or air supply. When the outdoor tent of the present application needs to be stored, the gas in the inflation cavity 511 of the main air duct 51 is directly discharged, which is convenient for the overall folding and storage of the outdoor tent, and has higher practicality.

[0049] In addition, in order to facilitate the flip installation of the fan 33, refer to Figure 1 and Figure 8 , multiple card seats 71 are fixedly connected to the side wall of the connecting sleeve 61, and the card seats 71 have vertically arranged card slots, and the top of the card seats 71 is fixedly connected to the limit block 72, and the mounting frame 62 is fixedly connected to multiple card blocks 73 corresponding to the multiple card seats 71. When it is necessary to flip and install the fan 33, the connecting sleeve 61 can be lifted up to separate the card blocks 73 from the card seats 71, and then the connecting sleeve 61 is removed, and the fan 33 is removed from the rotating shaft 31, and then the fan 33 is flipped over so that the other end of the card sleeve 4 is screwed to the rotating shaft 31, so that the airflow direction can be changed when the fan 33 rotates; then the connecting sleeve 61 is put outside the fan blade, and the card seats 71 on the connecting sleeve 61 are aligned with the card blocks 73 on the mounting frame 62, and the connecting sleeve 61 is vertically pressed down so that the card blocks 73 slide in the card seats 71 until they are tightly against the limit blocks 72, so that the normal installation of the connecting sleeve 61 can be achieved.

[0050] The implementation principle of a ventilated and breathable outdoor tent in the embodiment of the present application is: After the outdoor tent of the present application is built, the mounting frame 62 is overlapped on the top of the tent frame 11, and the inflation cavity 511 of the main air duct 51 is inflated and the main air duct 51 and the connecting sleeve 61 are connected. At this time, the multiple heat collecting tubes 2 arranged obliquely on the mounting frame 62 absorb solar energy, which can quickly heat the fluid medium in the heat collecting tube 2. After being heated, the fluid medium is heated and vaporized into water vapor and flows from the pressure relief pipe 21 to the power tank 3, and impacts the blades 32 on the rotating shaft 31 with a certain kinetic energy; under the action of the multiple heat collecting tubes 2, the multiple pressure relief pipes 21 spray water vapor with kinetic energy to impact the blades 32 corresponding to the rotating shaft 31, which can drive the rotating shaft 31 to rotate, and then drive the blades of the fan 33 at the lower end of the rotating shaft 31 to rotate. The blades of the fan 33 can form airflow when rotating, and actively circulate the air in the tent body 12 with the external air through the main air duct 51, which can greatly promote the ventilation and air permeability effect of the outdoor tent of the present application.

[0051] In this process, water vapor is liquefied in the power tank 3 after impacting the blades 32, and the internal pressure of the power tank 3 increases during the process of being filled with water vapor, so that the liquefied clean water flows back to the heat collecting tube 2 through the capillary 22, and the siphon effect of the capillary 22 can also promote the liquefied clean water to flow back to the heat collecting tube 2; after absorbing solar energy, the heat collecting tube 2 continues to heat the clean water flowing back in the heat collecting tube 2 to generate water vapor again. Such a cycle can form a continuous flow of water vapor impacting the blades 32 in the power tank 3, so that the blades of the fan 33 keep rotating, thereby ensuring the continuous ventilation and air permeability effect of the outdoor tent of the present application, especially during the day when solar energy is sufficient, the thermal drive module of the present application can maintain continuous and stable operation without the aid of an external power supply.

[0052] At the same time, by flipping the fan 33 for installation, the thermal drive module can be used to draw air outward from the tent body 12, or to deliver warm air inward, thereby making full use of the heat energy released by the evaporation of water vapor in the power tank 3 and the buffer tank 34, which can be ventilated and heated by wind, greatly improving the flexibility and comfort of the outdoor tent of the present application when used.
