DETAILED DESCRIPTION OF THE INVENTION
[0012] The heating cushion for fishing disclosed in the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0014] The oil stove (10) generates a flame by burning fuel.
[0015] As an embodiment of an oil furnace (10), the oil furnace (10) includes a fuel tank (11) having a fuel injection port (not shown) and filled with fuel; a burner port (12) installed above the fuel tank (11) and injecting vaporized fuel to form a flame; a bracket (13) supported on the upper part of the fuel tank (11); a fuel tank pressurizing device (14) provided in the fuel tank (11) to apply pressure to the inside of the fuel tank (11); a connecting pipe (15) connecting the fuel tank (11) and the burner port (12); a flame regulating valve (16) connected to the connecting pipe (15); and a cleaning cap (17) connected to one side of the connecting pipe (15) for cleaning the inside of the connecting pipe.
[0016] The shape of the fuel tank (11) can be embodied in various ways. The fuel injection port consists of an injection port and a lid for opening and closing the injection port, and a safety valve (not shown) for discharging pressure when the internal pressure of the fuel tank is too high is provided on the lid.

In the circumferential direction of each virtual circle, the plurality of injection holes are arranged at regular intervals. The injection holes (3) provided on the upper part (2) of the recess are preferably larger in size from the center point to the edge. Therefore, when the vaporized fuel flowing through the flow path of the burner port (12) is ejected through the injection holes (3) of the upper part (2) of the recess, the injection amount of the vaporized fuel ejected through each injection hole (3) is uniform, and a uniform flame in a complete combustion state can be formed.
[0018] The fuel tank pressurizing device (14) includes a manual piston (4) that penetrates one side of the fuel tank (11), and the user applies pressure to the inside of the fuel tank (11) containing a certain amount of fuel by moving the manual piston (4) back and forth. The said configuration is a known technique.
[0019] The connecting pipe (15) includes a vaporization preheating component (1); the vaporized fuel passing through the vaporization preheating component (1) is preheated by heating through the vaporization preheating component (1).
[0020] When generating a flame in the oil furnace (10), first fill the fuel tank (11) with a set amount of fuel. Then, with the fire control valve (16) closed, move the manual piston (4) on the fuel tank pressurizing device (14) back and forth a set number of times to pressurize the interior of the fuel tank (11). Immediately afterwards, use a heating appliance to heat the vaporization preheating section (1) of the connecting pipe (15) for a set time. If the fire control valve (16) is opened, the fuel pressurized and vaporized in the fuel tank (11) will be preheated through the connecting pipe (15) and sprayed through the spray holes (3) of the burner port (12) to burn into a flame.
[0021] The water tank (20) is detachably mounted on the oil furnace (10), and the water inside it is heated by the flame of the oil furnace (10).
[0022] As an embodiment of the water tank (20), the water tank (20) is preferably cylindrical with a blocked bottom and an open top. That is, the water tank (20) includes a cylindrical box body and a bottom plate that blocks the bottom of the cylindrical box body. The upper part of the water tank (20) is preferably covered with a lid (21).
[0023] The hose - built - in cushion (30) has a hose inside.
[0024] As an embodiment of the hose - built - in cushion (30), the hose - built - in cushion (30) includes a cushion cover (32), a heat - insulating interior material (33) filling the inside of the cushion cover (32), and a hose (31) provided throughout the inside of the cushion cover (32). The inflow end and the outflow end of the hose (31) are connected to connectors provided on the cushion cover. The hot water heated in the water tank (20) will flow into the hose (31) from the inflow end, and the water circulating inside the hose - built - in cushion (30) will then flow from the outflow end of the hose (31) to the water tank (20) side.
[0025] As an embodiment of the cushion cover (32), the cushion cover is preferably square to cover a fishing seat.
[0026] The circulating hose device (40) connects the water tank (20) and the hose - built - in cushion (30) to circulate the hot water heated in the water tank (20) through the hose (31) inside the hose - built - in cushion (30). The circulating hose device (40) includes a water pump (41), and is characterized in that it uses the electric energy generated in the thermoelectric device (50) to quickly pump the hot water so that the hot water in the water tank (20) can circulate quickly.
[0027] As an embodiment of the circulating hose device (40), the circulating hose device (40) includes: an outflow hose (42), which is characterized by connecting one side of the water tank (20) and one side of the hose (31) of the hose-integrated seat (30), and hot water from the water tank (20) flows out from the hose (31) of the hose-integrated seat (30); an inflow hose (43), which is characterized by connecting the other side of the water tank and the other side of the hose (31) of the hose-integrated seat (30), and the hot water that has lost heat after finally circulating through the hose (31) of the hose-integrated seat (30) will flow into the water tank (20) through this inflow hose; a water pump (41), which is characterized by connecting to one side of the outflow hose (42) and pumping out hot water by using the electricity generated in the thermoelectric device (50).
[0028] Preferably, a control device (70) is designed to be provided below the oil furnace (10). When the control device (70) is provided below the oil furnace (10), a part of the outflow hose (42) and the inflow hose (43) will be located inside the housing of the control device (70), and the water pump (41) will be connected to a part of the outflow hose (42) located inside the housing. A measuring device (not shown) for measuring the temperature and flow rate of hot water, etc. is provided inside the housing of the control device (70). As an embodiment of the measuring device, the measuring device includes: a temperature sensor connected to the circulating hose device (40) for measuring the temperature of hot water and a flow meter for measuring the flow rate.
[0029] The thermoelectric device (50) is installed below the water tank (20) and generates electric energy through the flame of the oil furnace (10).
[0030] As an embodiment of the thermoelectric device (50), the thermoelectric device (50) includes: a thermoelectric element installed below the water tank (20). When the thermoelectric element is heated, free electrons gain energy and use this energy to generate electromotive force, and the thermoelectric element includes a thermoelectric generator (TEG, Thermoelectric Generator) module. This technology is a known technology, so the relevant specific description is omitted. Preferably, there is one or more thermoelectric elements.
[0031] The fuel tank pressure regulating device (60) pumps air using the electric energy generated in the thermoelectric device (50) to keep the internal pressure of the fuel tank (11) in the oil furnace (10) at a set pressure. That is, as the fuel in the fuel tank (10) burns through the burner port (12), the amount of fuel filled inside the fuel tank (11) gradually decreases, the space inside the fuel tank (11) gradually increases, the internal pressure of the fuel tank (11) also gradually decreases, and the firepower gradually weakens; at this time, the fuel tank pressure regulating device (60) detects the internal pressure of the fuel tank (11), and when the pressure is less than the set pressure, it pumps air into the fuel tank (11) to keep the internal pressure of the fuel tank (11) at the set pressure. At the same time, when the internal pressure of the fuel tank (11) exceeds the set pressure, the fuel tank pressure regulating device (60) discharges part of the pressure to keep the internal pressure of the fuel tank (11) at the set pressure.
[0032] As an embodiment of the fuel tank pressure regulating device, the fuel tank pressure regulating device (60) includes: a pressure supply pipe (61) communicating with the inside of the fuel tank (11); a pressure sensor (62) installed on one side of the pressure supply pipe (61) for detecting the internal pressure of the fuel tank (11); an air pump (63) connected to the pressure supply pipe (61) for pumping air into the fuel tank (11) using the electric energy generated by the thermoelectric device (50); and a detection valve (64) provided on the pressure supply pipe (61), specifically located between the air pump (63) and the pressure sensor (62). On the other hand, in order to be located between the detection valve (64) and the pressure sensor (62), an exhaust valve (65) is preferably further provided in the pressure supply pipe (61).
[0033] The detection valve (64) allows gas to move from the air pump (63) side to the fuel tank (11) side, but prevents gas from moving from the fuel tank (11) side to the air pump (63) side.
[0034] The pressure supply pipe (61) is connected to any position that can communicate with the inside of the fuel tank (11). That is, the end of the pressure supply pipe on the side where the pressure sensor (62) is provided can be connected to any position of the fuel tank (11).
[0035] The pressure sensor (62), the air pump (63), and the exhaust valve (65) are connected to the control device (70). The control device (7) is connected to the heating temperature regulating device (G).
[0036] In the oil tank pressure regulating device (60), the pressure sensor (62) is used to detect the internal pressure of the oil tank (11). When the internal pressure of the oil tank (11) is lower than the set pressure, the air pump (63) is started to pump air; the pumped compressed air is injected into the oil tank (11) through the pressure supply pipe (61), so that the internal pressure of the oil tank (11) is maintained at the set pressure. On the other hand, when the internal pressure of the oil tank (11) is higher than the set pressure, the exhaust valve (65) is opened to discharge the internal pressure of the oil tank (11) to the outside until the internal pressure of the oil tank (11) reaches the set pressure state, and then the exhaust valve (65) is closed to maintain the internal pressure of the oil tank (11) at the set pressure. As an embodiment, when the pressure detected by the pressure sensor (62) is lower than the set value, the air pump (63) starts to start until the internal pressure of the oil tank (11) reaches the set pressure. As another embodiment, the air pump (63) can be periodically started at a set time interval to apply pressure to the inside of the oil tank (11) at the set interval. In this case, a timer can be added and the pressure sensor (62) is not provided.
[0037] When the oil tank pressure regulating device (60) is connected to the oil tank (11), the multifunctional loading and unloading valve (90) can be used to detachably connect the oil tank pressure regulating device (60). When the multifunctional loading and unloading valve (90) is connected to the oil tank pressure regulating device (60), the oil tank pressure regulating device (60) and the oil tank (11) can be connected, and when the multifunctional loading and unloading valve (90) is separated from the oil tank pressure regulating device (60), the flow path is blocked to prevent the inside of the oil tank (11) from being connected to the outside.
[0038] As an embodiment of the multifunctional loading and unloading valve (90), Figure 4 As shown, the multifunctional loading and unloading valve (90) comprises: a valve housing (91) provided with a through flow path along its length; a valve body (92) movably inserted into the through flow path of the valve housing (91) along its length; a spring (93) arranged on one side of the valve body (92) and elastically supporting the valve body (92); a sealing member (94) arranged between the valve body (92) and the through flow path of the valve housing (91) and blocking or connecting the through flow path through the up and down movement of the valve body (92); a fastening cover (95) connected to the valve housing (91) in a manner of wrapping around the valve housing (91) and assembled to the connecting portion (5) on the oil tank (11); and a joint (96) connected to the fastening cover (95) and at one end of the loading and unloading oil tank pressure regulating device (60).
[0039] The connecting portion (5) of the oil tank (11) is provided with a through hole on one side of the oil tank (11), protruding from a direction perpendicular to the edge of the through hole, and a male thread is provided on the outer peripheral surface of the protruding portion.
[0040] The end of the pressure supply pipe (61) of the fuel tank pressure regulating device (60) is provided with a connector (66), and the connector (66) is preferably detachable from the joint (96).
[0041] When the fuel tank (11) and the connection part (5) are combined with the multi-functional loading and unloading valve (90), in the state where the valve housing (91) is inserted into the inside of the connection part (5) of the fuel tank (11), the fastening cover (95) is fixed to the connection part (5). As described above, in the state where the multi-functional loading and unloading valve (90) is combined with the connection part (5) of the fuel tank (11), as Figure 5 shown, the valve body (92) is upwardly pressurized by the elastic force of the spring (93), the valve body (92) applies pressure to the sealing member (94), and further the sealing member (94) blocks the through-flow path, and finally blocks the inside of the fuel tank (11) and the outside of the multi-functional loading and unloading valve (90).
[0042] When the fuel tank pressure regulating device (60) is connected to the multi-functional loading and unloading valve (90), as Figure 4 shown, the end of the pressure supply pipe (61) of the fuel tank pressure regulating device (60), that is, the connector (66), is inserted and installed into the joint (96) of the multi-functional loading and unloading valve (90). When the end of the pressure supply pipe (61) is inserted into the joint (96) of the multi-functional loading and unloading valve (90), the end of the pressure supply pipe (66), that is, the connector (66), presses the upper end of the valve body (92), thereby releasing the pressure applied to the sealing member (94), and the sealing member (94) is connected to the through-flow path, so that the pressure supply pipe (61) of the fuel tank pressure regulating device (60) and the inside of the fuel tank (11) are communicated. On the other hand, if the end of the pressure supply pipe (61) of the fuel tank pressure regulating device (60) is separated from the joint (96) of the multi-functional loading and unloading valve (90), the valve body (92) will move to its original position and press the sealing member (94), and further block the through-flow path, cutting off the inside and outside of the fuel tank (11).
[0043] Preferably, an assembly composed of an oil furnace (10), a water tank (20), a thermoelectric device (50), a fuel tank pressure regulating device (60), and a control device (70) is installed by an installation appliance (80). The installation appliance (80) includes: a tripod (81), a plurality of hooks (82) coupled to each leg of the tripod (81); a plurality of hanging rings (83) arranged at regular intervals in the circumferential direction on the upper outer peripheral surface of the water tank (20), and a chain (84) connecting the hanging rings.
[0044] The functions and effects of the heating seat cushion for fishing according to the present invention will be described below.
[0045] First, place the hose - built - in seat cushion (30) at a position where it can cover the backrest and the support plate of the fishing seat (100). After separating a certain distance from the fishing seat (100) equipped with the hose - built - in seat cushion (30), assemble the mounting appliance (80), and install the assembly composed of the oil stove (10), the water tank (20), the thermoelectric device (50), the fuel tank pressure regulating device (60), and the control device (70) on the mounting appliance (80). Then, inject an appropriate amount of water into the water tank (20), start the oil stove (10), and generate a flame through the burner port (12) of the oil stove (10). The water injected into the water tank (20) is heated by the flame generated from the burner port (12) of the oil stove (10). The thermoelectric device (50) uses the flame of the burner port (12) to generate electric energy, which is supplied to the air pump (63) of the fuel tank pressure regulating device (60) and the water pump (41) of the circulating hose device (40). With the power supply and startup in the water pump (80), the hot water heated in the water tank (20) flows through the outflow hose (42) of the circulating hose device (40) and is supplied to the inner hose (31) in the hose - built - in seat cushion (30) covering the fishing seat (100). The hot water supplied to the hose (31) flows through the hose (31) arranged throughout the hose - built - in seat cushion (30), and transfers the heat of the hot water to the hose - built - in seat cushion (30). The hot water passing through the hose (31) in the entire hose - built - in seat cushion (30) finally re - flows into the water tank (20) through the inflow hose (43) of the circulating hose device (40). The water re - flowing into the water tank (20) is heated in the water tank (20) by the flame of the oil stove (10) and circulates repeatedly according to the above - mentioned circulation path to heat the hose - built - in seat cushion (30). On the other hand, as the fuel in the fuel tank (10) continuously vaporizes and burns, the space inside the fuel tank (11) gradually increases and the firepower gradually weakens; at this time, the fuel tank pressure regulating device (60) detects the internal pressure of the fuel tank (11). When the pressure drops, it pumps air into the inside of the fuel tank (11) to keep the internal pressure of the fuel tank (11) at the set pressure and maintain the initial firepower state.
[0046] When fishing, the angler sits on the hose - built - in seat cushion (30) covering the fishing seat (100) and can enjoy the fishing pleasure in a warm state.
[0047] When anglers (users) think that the temperature of the hose - built - in cushion (30) is low, they can increase the temperature of the heating temperature adjustment device (G). At this time, the air pump (63) of the fuel tank pressure adjustment device (60) will pump air, inject high - pressure air into the interior of the fuel tank (11), increase the internal pressure of the fuel tank (11), increase the flame generated through the fire port (12), raise the temperature of the water tank (20), and thus increase the temperature of the hose - built - in cushion (30). When anglers think that the temperature of the hose - built - in cushion (30) is high, they can lower the temperature of the heating temperature adjustment device (G). At this time, the exhaust valve (65) of the fuel tank pressure adjustment device (60) will discharge the internal pressure to reduce the internal pressure of the fuel tank (11), reduce the flame generated through the fire port (12), and then lower the water temperature in the water tank (20), and further lower the temperature of the hose - built - in cushion (30).
[0048] When the user only uses the oil stove (10), the water tank, the control device, and the fuel tank pressure adjustment device can be removed from the oil stove, and then the oil stove can be used.
[0049] As described above, the present invention has the following beneficial effects: Using the flame of the oil stove (10) to heat the water inside the water tank (20), and continuously supplying the heated hot water in the water tank (20) to the hose - built - in cushion (30) provided on the fishing seat (100), so as to continuously provide heat at the required temperature to the anglers sitting on the fishing seat (100) provided with the hose - built - in cushion (30). Even when fishing outdoors in cold seasons such as early spring, late autumn, and winter, anglers can sit on the fishing seat (100), enjoy fishing while keeping warm. This can not only improve the satisfaction of anglers, but also has a simple structure, is convenient to carry and use.
[0050] In addition, according to the technical solution of the present invention, since the firepower of the oil stove (10) can maintain the set firepower, the water temperature in the water tank (20) can be evenly maintained. Therefore, the hose - built - in cushion (30) placed on the fishing seat (100) can also evenly and continuously maintain the set temperature, thereby improving the reliability of the product.
[0051] In addition, according to the technical solution of the present invention, the user (angler) can arbitrarily adjust the temperature of the hose - built - in cushion (30), which can enhance the comfort level.
