Description

Technical Field

[0001] The utility model relates to the technical field of spray pots, in particular to an opening and closing structure of a sealing cover of a spray pot. Background Art

[0002] A spray pot is a device for spraying liquids, which is widely used in gardening, horticulture, family breeding and other construction, industrial processing and other occasions that require pressure spraying of liquids.

[0003] A pneumatic spray pot is a type of spray pot, most of which are a combination of a pot cover and a pot body, and a pressurizing component is installed on the pot cover. For example, as described in the text of a portable spray pot with a Chinese patent publication number of CN2734342Y, a bottle body is provided, and an end cap is installed at the open end of the bottle body, and a nozzle assembly, a gas cylinder assembly, and a switch assembly are installed on the end cap. When adding water to this type of spray pot, the end cap needs to be unscrewed before water can be added to the inner cavity of the bottle body. However, due to the large number of components on the end cap, it is inconvenient to unscrew the end cap and place it after unscrewing, which affects the convenience of watering the spray pot. There is also a water injection port on the pot cover, and a sealing cover is provided on the top of the water injection port, as described in the text of a foam spray pot with a Chinese patent publication number of CN212681389U. Water can be injected into the spray pot from the water injection port after the sealing cover on the top is opened, without opening the pot cover as a whole. Although the method of setting a water filling port on the pot lid can improve the convenience of water filling, it is often difficult to ensure the sealing and connection stability between the sealing cover and the water filling port in actual implementation, especially in a pneumatic spray pot. The internal pressure of the spray pot is relatively high, and the sealing cover is easily separated from the water filling port under the action of pressure, so it needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an opening and closing structure of a sealing cover of a watering can, which can not only realize the convenient water filling of the watering can, but also effectively ensure the sealing of the sealing cover and the water filling port and the stability of the connection.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A watering pot sealing cover opening and closing structure comprises a watering pot body and a water inlet arranged on the top of the watering pot body, wherein a lower sealing cover for opening and closing the bottom of the water inlet is hingedly connected to the inner top of the watering pot body through a horizontal hinge seat, and an upper cover for opening and closing the top of the lower water inlet is movably connected to the top of the watering pot body, wherein a first magnetic body and a second magnetic body are fixed to the upper cover and the lower sealing cover respectively; when the upper cover is in a closed state, the first magnetic body and the second magnetic body are within the magnetic attraction range of each other.

[0007] As a further solution of the utility model: a pressure relief port is also provided on the top of the spray pot body, and the pressure relief port is elastically blocked by a pressure relief component, and the pressure relief component is located on the movable path of the upper cover, and the pressure relief port is opened by squeezing the pressure relief component when the upper cover is opened.

[0008] As a further solution of the utility model: the pressure relief assembly includes a guide column that passes through the pressure relief port in a vertical direction, the guide column is of a thin-at-top and thick-at-bottom structure, and a sealing ring is sleeved on the column body of the guide column located on the inner side of the spray pot body, and the guide column and the sealing ring elastically slide upward and seal the pressure relief port.

[0009] As a further solution of the utility model: the top of the guide column is bent downward on both sides to form an arched spring sheet, and the two ends of the spring sheet elastically abut the top of the spray pot body and push the guide column and the sealing ring to slide upward to block the pressure relief port.

[0010] As a further solution of the present invention: the first magnetic body and the second magnetic body are both magnets.

[0011] As a further solution of the utility model: the lower sealing cover is made of rubber.

[0012] As a further solution of the utility model: the lower sealing cover is made of plastic material, and a sealing ring is installed on the top of the lower sealing cover.

[0013] As a further solution of the utility model: the upper cover is hinged to the top of the spray pot body around a horizontal axis.

[0014] As a further solution of the utility model: the upper cover slides horizontally linearly on the top of the spray pot body.

[0015] As a further solution of the utility model: the upper cover is rotatably fitted around the vertical axis on the top of the spray pot body.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. A water inlet is set at the top of the spray pot body, and the bottom of the water inlet is sealed from bottom to top by the lower sealing cover, so that the water inlet is sealed and the connection stability is guaranteed when the internal pressure of the spray pot body is high; and the top of the water inlet is sealed by the upper cover, which can prevent the water inlet and the lower sealing cover from being dustproof. In addition, the first magnetic body and the second magnetic body are fixed on the upper cover and the lower sealing cover respectively; when the upper cover is in a closed state, the first magnetic body and the second magnetic body are within the magnetic attraction range of each other, so that when the upper cover is closed, the lower sealing cover can be rotated to a closed state under the action of the magnetic attraction force, thereby quickly closing the upper cover and the lower sealing cover after the water filling is completed.

[0018] 2. A pressure relief port is also provided on the top of the spray pot body, and the pressure relief component is located on the movable path of the upper cover, and the pressure relief port is opened by squeezing the pressure relief component when the upper cover is opened. When the upper cover is opened, the pressure inside the spray pot body 1 is released. At this time, the first magnetic body and the second magnetic body are also beyond the range of mutual magnetic attraction, so that the lower sealing cover can be swung downward and opened under the action of its own gravity. Therefore, when the upper cover is opened and closed, the lower sealing cover can be opened and closed synchronously, which further improves the convenience of water injection into the spray pot body.

[0019] 3. The pressure relief component uses a guide column and a sealing ring to elastically seal the pressure relief port from bottom to top, which can better seal the pressure relief port when the internal pressure of the spray pot body is high. In addition, the pressure relief component uses the method of opening from top to bottom, which is also convenient for driving the pressure relief component to open the pressure relief port when the upper cover is opened.

[0020] 4. The top of the guide column is bent downward on both sides to form an arched spring sheet, which can not only elastically abut the top of the spray pot body with both ends of the spring sheet and push the guide column and the sealing ring to slide upward to block the pressure relief port, but also deform the spring sheet when it is subjected to downward pressure, so that the guide column and the sealing ring move downward to open the pressure relief port. In addition, the setting of the spring sheet arched structure also makes it easier for the upper cover to smoothly press the spring sheet down to a horizontal position.

[0021] 5. Both the first magnetic body and the second magnetic body are magnets, and the mutual magnetic attraction of the two magnets has a good adsorption effect.

[0022] 6. The lower sealing cover can be made of rubber material, and the elastic properties of the material itself can be used to achieve a good seal on the water inlet.

[0023] 7. The lower sealing cover can also be made of plastic material, and a sealing ring can be used to achieve a good seal on the water injection port. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:

[0033] The specific structure of the utility model refers to Figure 1-6 As shown, its main structure includes a spray pot body 10, a water injection port 11 arranged at the top of the spray pot body 10, and an upper cover 20 and a lower sealing cover 30 for opening and closing the top and bottom of the sealed water injection port 11. Among them, the lower sealing cover 30 is hinged to the inner top of the spray pot body 10 through a horizontal hinge seat, so as to open and close the bottom of the water injection port 11. By sealing from bottom to top by the lower sealing cover 30, the lower sealing cover 30 can better seal the bottom of the water injection port 11 under the impact of air pressure or water flow in the spray pot body 10; especially when the spray pot body 10 is a pneumatic spray pot, the lower sealing cover 30 is pressurized by the gas-filling structure of the spray pot body 10. When the internal pressure of the spray pot body 10 is greater, the internal pressure of the spray pot body 10 will squeeze the lower sealing cover 30 and the water injection port 11 to abut more tightly, so that the sealing performance of the water injection port 11 is better and the sealing stability of the lower sealing cover 30 and the water injection port 11 is better. The upper cover 20 is movably connected to the top of the spray pot body 10 to open and close the top of the water injection port 11, and can protect the water injection port 11 from dust, preventing dust from falling on the water injection port 11 and the lower sealing cover 30 and then being transported into the spray pot body 10 during the water injection process. In addition, the first magnetic body 21 and the second magnetic body 32 are fixed to the upper cover 20 and the lower sealing cover 30 respectively; when the upper cover 20 is in a closed state, the first magnetic body 21 and the second magnetic body 32 are within the magnetic attraction range of each other, so that when the upper cover 20 is closed, the first magnetic body 21 and the second magnetic body 32 generate mutual magnetic attraction, so that the lower sealing cover 30 rotates to a closed state under the action of the magnetic attraction, thereby quickly closing the upper cover 20 and the lower sealing cover 30 after the water injection is completed.

[0034] Specifically, the first magnetic body 21 and the second magnetic body 32 are both magnets, and the mutual magnetic attraction of the two magnets has a good adsorption effect. Of course, one of the first magnetic body 21 and the second magnetic body 32 can also be a magnet and the other can be made of iron, which can also achieve good adsorption between the first magnetic body 21 and the second magnetic body 32.

[0035] On the basis of the above, the lower sealing cover 30 is opened quickly when the pressure in the spray pot body 10 is high. Figure 2-4 As shown, a pressure relief port 12 is also provided on the top of the spray pot body 10, and the pressure relief port 12 is elastically blocked by a pressure relief component 40, and the pressure relief component 40 is located on the movable path of the upper cover 20, and the pressure relief component 40 is squeezed to open the pressure relief port 12 when the upper cover 20 is opened, and when the upper cover 20 is closed, the pressure relief component 40 continues to elastically reset and block the pressure relief port 12. During use, when the upper cover 20 is opened, the pressure inside the spray pot body 10 is relieved. At this time, the first magnetic body 21 and the second magnetic body 32 are also beyond the range of mutual magnetic attraction, so that the lower sealing cover 30 can swing downward and open under its own gravity. Therefore, when the upper cover 20 is opened and closed, the lower sealing cover 30 can be opened and closed synchronously, which further improves the convenience of water injection into the spray pot body 10.

[0036] Further, such as Figure 4 As shown, the pressure relief component 40 includes a guide column 41 that passes through the pressure relief port 12 in a vertical direction. The guide column 41 is of a thin-upper-bottom thick structure, and a sealing ring 42 is sleeved on the column body of the guide column 41 located on the inner side of the spray pot body 10. The sealing ring 42 is supported by the thick section at the lower part of the guide column 41, so that when the guide column 41 is subjected to an elastic force, the sealing ring 42 can be elastically brought upward to abut against the outer edge of the pressure relief port 12 to block the pressure relief port 12. The pressure relief component 40 adopts the method of elastically sealing the pressure relief port 12 from bottom to top, which can better seal the pressure relief port 12 when the internal pressure of the spray pot body 10 is relatively high. In addition, the pressure relief component 40 adopts the method of opening from top to bottom, which is also convenient for driving the pressure relief component 40 to open the pressure relief port 12 when the upper cover 20 is opened.

[0037] Furthermore, if Figure 4As shown, the top of the guide column 41 is bent downward on both sides to form an arched spring sheet 43, and the two ends of the spring sheet 43 elastically abut the top of the spray pot body 10 and push the guide column 41 and the sealing ring 42 to slide upward to block the pressure relief port 12, and when the spring sheet 43 is subjected to downward pressure, the spring sheet 43 is deformed and the guide column 41 and the sealing ring 42 move downward to open the pressure relief port 12. In addition, the setting of the arched structure of the spring sheet 43 also facilitates the upper cover 20 to smoothly press the spring sheet 43 down to the horizontal. In addition, the top of the spray pot body 10 is provided with a positioning slide 13 arranged along the length direction of the spring sheet 43, and the two ends of the spring sheet 43 are located in the groove cavity of the positioning slide 13, which ensures that the two ends of the spring sheet 43 can slide along the fixed length direction, so that the length direction of the spring sheet 43 remains unchanged under normal conditions, so as to ensure that the spring sheet 43 can be smoothly squeezed and deformed each time the upper cover 20 is opened. Moreover, the positioning slot 13 is set so that both ends of the spring piece 43 are located in the slot cavity of the positioning slot 13, so that the upper cover 20 can smoothly squeeze the spring piece 43 to deform downward when sliding along the horizontal plane and rotating around the vertical axis. Of course, in order to ensure that the length direction of the spring piece 43 remains unchanged under normal conditions, that is, to prevent the spring piece 43 from rotating along the vertical axis, in actual implementation, a method of limiting the rotation of the guide column 41 can also be adopted. Of course, this method can be used together with the positioning slot 13 or used alone, and both can prevent the spring piece 43 from rotating along the vertical axis. Specifically, for example, the guide column 41 is set to a regular polygonal structure with a radial cross section, and the hole profile of the pressure relief port 12 is adapted to the outer profile of the guide column 41, so that the guide column 41 only slides in a vertical manner, which can also effectively limit the rotation of the spring piece 43 along the vertical axis.

[0038] Of course, the pressure relief assembly 40 can also adopt other implementations, such as, on the basis of including the guide column 41 and the sealing ring 42, an arched flange is provided on the top of the guide column 41, and the groove depth of the positioning groove 13 is set to accommodate the flange, and an extrusion spring is provided in the positioning groove 13 to squeeze the guide column 41 to slide elastically upward.

[0039] On the basis of the above, the lower sealing cover 30 can be made of rubber material, so that the lower sealing cover 30 can ensure the sealing of the water injection port 11 when closed by relying on its own elastic properties. Of course, silicone materials and polymer materials with good elasticity can be used. In addition, Figure 2 As shown, the lower sealing cover 30 can also be made of plastic material, and a sealing ring 31 is installed on the top of the lower sealing cover 30. The sealing of the water injection port 11 can also be effectively guaranteed by the setting of the sealing ring 31.

[0040] On the basis of the above, if Figure 1 , Figure 5 and Figure 6 As shown, the upper cover 20 has the following three implementation modes:

[0041] Embodiment 1, as Figure 1-3 As shown, the upper cover 20 is hinged on the top of the spray pot body 10 around a horizontal axis. The upper cover 20 is flipped open, and a flange is set at the hinge axis of the upper cover 20. The flange is used to press the pressure relief component 40 downward during the flipping process of the upper cover 20, so as to drive the pressure relief component 40 to open the pressure relief port 12.

[0042] Embodiment 2, as Figure 5 As shown, the upper cover 20 slides horizontally and linearly on the top of the spray pot body 10. During the horizontal linear sliding process of the upper cover 20, the pressure relief component 40 is squeezed along the curved surface of the spring 43 to slide downward as a whole, thereby driving the pressure relief component 40 to open the pressure relief port 12.

[0043] Embodiment 3, as Figure 6 As shown, the upper cover 20 rotates around the vertical axis and fits on the top of the spray pot body 10. During the rotation of the upper cover 20, the pressure relief assembly 40 is squeezed along the curved surface of the spring piece 43 to slide downward as a whole, thereby driving the pressure relief assembly 40 to open the pressure relief port 12.

[0044] Of course, for those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0045] In addition, it should be understood that although this specification is described in accordance with the implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art. The technology, shape, and structure parts not described in detail in this utility model are all well-known technologies.
