[0001] The present application relates to the technical field of daily necessities, and in particular to a pressure kettle cover and a water cup having the pressure kettle cover. Background Art

[0002] A pressure kettle is a kettle that operates on the principle of air pressure. It usually changes the air pressure inside the kettle by heating or pressing, thereby pushing the water upward or outward. Its functions are generally integrated into the kettle lid.

[0003] Publication No. CN219962587U discloses a pressure kettle lid, pressure kettle, and cooling accessory. By rotating the water outlet, the rotating portion is adjusted to block the pressure relief channel. By pressing the airbag, the water in the kettle body is sent out through the water supply channel and the water outlet channel. During actual production and use, the following problems were found:

[0004] 1) The actual production of airbags is difficult and the cost is high, which is not conducive to market expansion.

[0005] 2) Under certain circumstances (for example, when the airbag is full of water), the opening flap at the bottom may cause water to flow back into the airbag through the opening flap when the airbag is pressed.

[0006] 3) When discharging water, since the water outlet of the water outlet channel is opened on the water outlet part, the water will flow along the water outlet part to the lid and the kettle body, which makes the user experience poor.

[0007] Based on this, this application aims to solve the above problems.

[0008] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0009] Based on this, the present application provides a pressure kettle cover and a water cup with the pressure kettle cover to solve one of the above technical problems.

[0010] The technical solution adopted by the present application to solve its technical problems is as follows: in the first aspect, a pressure kettle lid comprises: a kettle lid, a water supply channel and a pressure relief channel which are connected from top to bottom, and an air channel is provided at the bottom of the kettle lid; a water outlet member rotates on the upper part of the kettle lid, and a water outlet channel is provided inside the kettle lid; a press-type air delivery device is installed inside the kettle lid, and is used to realize the downward air delivery function through the air channel by pressing operation, comprising a lower air cylinder and an upper air cylinder, the upper air cylinder slides up and down inside the lower air cylinder, a spring is provided between the two, an air delivery hole which communicates with the air channel is provided at the bottom of the lower air cylinder, a relatively closed space is formed between the upper air cylinder and the lower air cylinder, and when the upper air cylinder is pressed, the press-type air delivery device outputs gas from the air delivery hole and the air channel to the outside; the water outlet member comprises a rotating part and a rod; when in use, the water outlet member rotates until the water outlet channel and the water supply channel are connected, and the pressure relief channel is closed; when in a closed state, the rotating part closes the water supply channel and the pressure relief channel.

[0011] In some embodiments, an elastic opening flap is fixed in the airway, and the elastic opening flap remains closed except when the push-type air delivery device is pressed. The upper part of the elastic opening flap is fixed on the lower air cylinder and remains connected to the air delivery hole.

[0012] In some embodiments, the upper air cylinder and the lower air cylinder are sealed by a sealing ring. The sealing ring is provided on the upper air cylinder, and its edge extends downwardly and fits against the inner wall of the lower air cylinder.

[0013] In some embodiments, a pressure cover is provided above the upper air cylinder, and the pressure cover slides inside the pot cover, and the upper air cylinder is pressed by pressing the pressure cover.

[0014] In some embodiments, a sliding groove is provided on the inner wall of the pot cover, and a limiting protrusion is formed on the pressure cover, and the limiting protrusion slides in the sliding groove.

[0015] In some embodiments, an elastic sheet is formed on the pressure cover, and the limiting protrusion is formed on the elastic sheet. The pressure cover can be removed by pressing the elastic sheet.

[0016] In some embodiments, a downwardly protruding mounting ring is formed at the bottom of the kettle lid, the air duct is placed in the mounting ring, a water blocking barrel is detachably mounted on the mounting ring, and a plurality of ventilation grooves are opened on the upper part of the water blocking barrel.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0034] In the examples of this application, please refer to Figure 1-7 As shown, the air pressure kettle cover and the water cup with the air pressure kettle cover mainly include: a kettle cover 1, which is provided with a water supply channel 2 and a pressure relief channel 3 that pass through the upper and lower parts, and an air channel 4 is provided at the bottom of the kettle cover 1; a water outlet member 5 is rotated on the upper part of the kettle cover 1, and a water outlet channel 6 that passes through both ends is provided inside the kettle cover; a press-type air delivery device 7 is installed inside the kettle cover 1, and is used to realize the downward air delivery function through the air channel 4 by pressing operation, including a lower air cylinder 702 and an upper air cylinder 701, and the upper air cylinder 701 slides up and down inside the lower air cylinder 702, and a pressure relief channel 3 is provided between the two. There is a spring 703, and an air delivery hole 8 communicating with the air channel 4 is provided at the bottom of the lower air cylinder 702. A relatively closed space is formed between the upper air cylinder 701 and the lower air cylinder 702. When the upper air cylinder 701 is pressed, the press-type air delivery device 7 outputs the gas from the air delivery hole 8 and the air channel 4 to the outside; the water outlet part 5 includes a rotating part 501 and a rod part 502; when in use, the water outlet part 5 rotates to the water outlet channel 6 to connect with the water delivery channel 2, and the pressure relief channel 3 is closed; when in the closed state, the rotating part 501 closes the water delivery channel 2 and the pressure relief channel 3.

[0035] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0036] like Figure 2 As shown, an elastic opening flap 9 is fixed in the airway 4. Except when the push-type gas delivery device 7 is pressed, the elastic opening flap 9 remains closed. The upper part of the elastic opening flap 9 is fixed on the lower gas cylinder 702 and remains connected with the gas delivery hole 8. When the push-type gas delivery device 7 is pressed, the gas between the upper gas cylinder 701 and the lower gas cylinder 702 will be delivered through the elastic opening flap 9.

[0037] like Figure 3 As shown, the upper cylinder 701 and the lower cylinder 702 are sealed by a sealing ring 10. The sealing ring 10 is arranged on the upper cylinder 701, and its edge extends downward and fits with the inner wall of the lower cylinder 702. The sealing ring 10 is used to ensure that when the upper cylinder 701 is pressed to slide, most of the air between the upper cylinder 701 and the lower cylinder 702 will not escape through any path other than the elastic opening flap 9.

[0038] Specifically, due to the characteristic that the edge of the sealing ring is inclined downward to contact the inner wall of the lower air cylinder 702, the sealing ring 10 only has a small area of ​​the extended part at the bottom in contact with the lower air cylinder 702. There is a gap between the upper and middle parts of the sealing ring 10 and the lower air cylinder 702. When the upper air cylinder 701 is pressed, the air in the upper and lower air cylinders 701 and 702 squeezes the sealing ring 10 from the inside out, and the sealing ring 10 will deform toward the lower air cylinder 702, squeezing the inner wall of the lower air cylinder 702. The internal gas is not easy to escape through the sealing ring 10. When the upper air cylinder 701 is released, the external air pressure is greater than the air pressure between the upper and lower air cylinders 701 and 702. The external air will squeeze the sealing ring 10 from the outside to the inside, and the sealing ring 10 will deform away from the lower air cylinder 702. The external air will be replenished from the gap between the sealing ring 10 and the inner wall of the lower air cylinder 702.

[0039] Furthermore, a pressure cover 11 is provided above the upper air cylinder 701 , and the pressure cover 11 slides inside the pot cover 1 . The upper air cylinder 701 is pressed by pressing the pressure cover 11 , thereby driving the upper air cylinder 701 to slide up and down.

[0040] Furthermore, the water outlet channel 6 is bent at the end of the rod 502 and extends outward. Specifically, the two ends of the water outlet channel 6 are the water inlet 601 and the water outlet 602, respectively. The water inlet 601 is at the rotating part 501, the water outlet 602 is at the rod 502, and the bent and extended part is at the water outlet 602.

[0041] Furthermore, a rotating seal 18 is provided on the pot lid 1. The rotating seal 18 is made of soft rubber material. The outer periphery of the rotating portion 501 of the water outlet part 5 maintains elastic contact with the rotating seal 18. Under the action of the rotating seal 18, when the water inlet 601 rotates to the water transfer channel 2, the two can fit tightly and maintain a seal.

[0042] Specifically, when in use, a straw is externally connected to or integrally formed on the lower end of the water delivery channel 2 .

[0043] like Figure 4 As shown, a slide groove 12 is provided on the inner wall of the pot cover 1, and a limiting protrusion 13 is formed on the pressure cover 11. The limiting protrusion 13 slides in the slide groove 12. Under the cooperation of the limiting protrusion 13 and the slide groove 12, the pressure cover 11 can only slide up and down within a limited range and cannot be separated from the pot cover 1.

[0044] Specifically, an elastic piece 14 is formed on the pressure cover 11 , and the limiting protrusion 13 is formed on the elastic piece 14 . The pressure cover 11 can be removed by pressing the elastic piece 14 , which facilitates disassembly and assembly.

[0045] like Figure 1-2 As shown, a downwardly protruding mounting ring 15 is formed at the bottom of the pot cover 1, and the airway 4 is placed in the mounting ring 15. A water blocking bucket 16 is detachably mounted on the mounting ring 15, and a plurality of ventilation grooves 17 are provided on the upper part of the water blocking bucket 16, wherein the elastic opening flap 9 is completely placed in the mounting ring 15, and the water blocking bucket 16 can block the water below the elastic opening flap 9, and the ventilation groove 17 is provided at the junction of the mounting ring 15 and the water blocking bucket 16, which plays a role in circulating the air inside and outside the water blocking bucket 16. Under the joint action of the mounting ring 15 and the water blocking bucket 16, even if the water submerges the water blocking bucket 16 and the mounting ring 15, it will not contact the elastic opening flap 9.

[0046] like Figure 5 As shown, an exhaust groove 20 is provided on the rotating portion 501 of the water outlet member 5 . When the water outlet member 5 is rotated, the exhaust groove 20 can be connected to the pressure relief channel 3 and the water delivery channel 2 .

[0047] like Figure 6-7 As shown, the present application proposes a water cup, comprising a kettle body 19 , on which the air pressure kettle cover 1 described in any of the above embodiments is mounted.

[0048] Working principle: When the water outlet 5 is not in use, it is placed horizontally on the lid 1. At this time, the water supply channel 2 and the pressure relief channel 3 are both closed by the rotating part 501, and the water in the kettle body 19 cannot flow out. When water needs to be taken out, the water outlet 5 is rotated. In the process of switching from the non-use state to the use state, the pressure relief channel 3 will first communicate with the exhaust groove 20 to complete the exhaust, and then be sealed by the rotating part 501 until the water outlet 5 cannot rotate. At this time, the water inlet 601 is in close contact with the water supply channel 2, and the water supply channel 3 is closed. The channel 2 is connected to the water outlet channel 6, the pressure relief channel 3 is closed, and then the upper air cylinder 701 is squeezed downward by pressing the pressure cover 11, so that the upper air cylinder 701 slides downward to squeeze the air. At this time, the spring 703 is compressed, and the elastic opening flap 9 opens, and the gas is transported downward into the kettle body 19. The air pressure in the kettle body 19 increases, and the water in the kettle body 19 is sent out through the straw and the water delivery channel 2 and the water outlet channel 6. The water is taken out, the pressure cover 11 is released, the spring 703 is restored, and the upper air cylinder 701 is reset.

To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
