[0023] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be connected through an intermediate medium, it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Please refer to Figures 1 to 4 The plastic bottle with a press type water outlet according to an embodiment of the present application comprises a bottle body 10, a bottle cap 20 connected with the bottle body 10, a water outlet pipe 30, a water collecting and filtering assembly 40, and an air valve 50 arranged in the bottle cap 20. The air valve 50 comprises a valve body 51 arranged in the bottle cap 20, a sealing element 52 sealingly connected with the bottle body 10 at the bottom of the valve body 51, a valve core 53 having one end communicated with the valve body 51 and the other end communicated with the bottle body 10 through the sealing element 52, and a pressing element 54 arranged at the top of the valve body 51 and penetrating the bottle cap 20. One end of the water outlet pipe 30 is arranged in the bottle body 10, and the other end penetrates the sealing element 52 and extends out from one side of the bottle cap 20. The water collecting and filtering assembly 40 comprises an intermediate pipe 41 communicated with the water outlet pipe 30 in the bottle body 10, and a plurality of water collecting pipes 42 communicated with the free end of the intermediate pipe 41. In this embodiment, the plastic bottle with a press type water outlet further comprises a filtering element, and the water collecting pipes 42 are communicated with the intermediate pipe 41 through the filtering frame.

[0025] The working principle of the pressing type water outlet plastic bottle is as follows: when the pressing piece 54 is not pressed, the air valve 50 is in a closed state; the valve core 53 closes the channel inside the valve body 51, and the liquid in the bottle cannot flow out under the action of atmospheric pressure; at this time, the liquid in the bottle is stored in the bottle body 10 through the water outlet pipe 30, the intermediate pipe 41 and the water collecting pipe 42, and when the pressing piece 54 on the top of the bottle cap 20 is pressed, the pressing piece 54 pushes the valve core 53 inside the valve body 51 downward; the valve core 53 moves downward, so that the channel inside the valve body 51 is opened, and the external air enters the valve body 51 through the pressing piece 54, and then enters the inside of the bottle body 10 through the valve core 53; as the air enters the bottle, the air pressure in the bottle increases; under the action of the air pressure difference, the liquid in the bottle is pressed into the water outlet pipe 30; the liquid is concentrated to the intermediate pipe 41 through the water collecting pipe 42, and flows upwards along the water outlet pipe 30 to the water outlet pipe 30 on the side of the bottle cap 20.

[0026] Compared with the prior art, the pressing type water outlet plastic bottle of the utility model adjusts the water outlet amount by controlling the pressing force and time; the liquid is discharged in small amount each time by gently pressing, and is suitable for the case that the liquid amount needs to be accurately controlled; the plurality of water collecting pipes 42 of the water collecting and filtering assembly 40 can fully collect the liquid in each corner of the bottle; even if the bottle is inclined or some liquid is left on the bottle bottom edge, etc., the water collecting pipe 42 can collect the liquid to ensure that the liquid can be smoothly guided to the water outlet pipe 30; the bottle cap 20 is clamped and connected with the bottle body 10, and the sealing piece 52 and the valve core 53 in the air valve 50 and the like can effectively prevent air from entering the bottle when not in use; the intermediate pipe 41 and the water collecting pipe 42 in the water collecting and filtering assembly 40 can play a role in filtering impurities during the liquid flow; if the liquid in the bottle contains some small particle impurities, when the liquid flows from the bottle body 10 to the water collecting pipe 42 through the intermediate pipe 41, the impurities can be intercepted on the filtering part.

[0027] Please refer to Figures 2 to 4The bottle cap 20 comprises a clamping section 21 clamped with the bottle body 10 and a cover section 22 arranged on the clamping section 21. The cover section 22 and the clamping section 21 are pivotally connected at one end and are clamped at the other end. The pressing member 54 comprises a sleeve part 540 sleeved on the valve body 51 and a pressing part 541 arranged on the top of the valve body 51. The pressing part 541 is sealingly connected with the sleeve part 540. The top of the pressing part 541 penetrates the cover section 22 and extends outward. The sleeve part 540 of the pressing member 54 is sleeved on the valve body 51, so that the pressing member 54 can be closely combined with the valve body 51 and can move up and down on the valve body 51. This ensures that the pressing member 54 will not shake or deviate from the central axis during pressing. The pressing part 541 is sealingly connected with the sleeve part 540, which can prevent external air from entering the air valve 50 from the connection between the pressing part 541 and the sleeve part 540, thereby ensuring the normal operation of the air valve 50. For example, this sealing connection can be achieved by using a sealing material such as a rubber sealing ring. When the pressing member 54 moves up and down, the sealing connection can still maintain good sealing performance. The top of the pressing part 541 penetrates the cover section 22 and extends outward, so that the user can conveniently operate the pressing member 54 with the bottle cap 20 closed. When the cover section 22 is closed, the extended part of the pressing part 541 is exposed outside the bottle cap 20. The user can operate the valve core 53 inside the air valve 50 by pressing this part without opening the bottle cap 20. When the user presses the pressing part 541, the pressing force will be transmitted to the valve core 53 inside the valve body 51 because the pressing part 541 is sealingly connected with the sleeve part 540 and the sleeve part 540 is sleeved on the valve body 51. The cover section 22 plays a certain protective role on the pressing member 54. When the bottle cap 20 is in the closed state, the cover section 22 covers the pressing member 54 to prevent accidental contact or damage of the pressing member 54 by external dust and sundries.

[0028] The gas valve 50 further comprises an elastic member 56 arranged on the clamping section 21. One end of the elastic member 56 is connected to the clamping section 21, and the other end is connected to the bottom of the sleeve joint portion 540. In this embodiment, the elastic member 56 is a spring. When the user presses the pressing portion 541 of the pressing member 54, the pressing portion 541 drives the sleeve joint portion 540 to move downward, thereby pushing the valve core 53 to open the passage of the gas valve 50, so that the liquid in the bottle can flow out; at this time, the elastic member 56 is stretched. Because one end of the elastic member 56 is connected to the clamping section 21, and the other end is connected to the bottom of the sleeve joint portion 540, the downward movement of the sleeve joint portion 540 causes the elastic member 56 to deform and store elastic potential energy. Once the user releases the pressing portion 541, the elastic member 56 will restore to its original state using the elastic potential energy it has stored; during the restoration process, the elastic member 56 will pull the sleeve joint portion 540 upward, causing the sleeve joint portion 540 to return to its original position; the resetting of the sleeve joint portion 540 also drives the pressing portion 541 connected thereto to return to its original position; the elastic member 56 can buffer the pressing force to some extent; when the user presses the pressing portion 541, the elastic member 56 will gradually stretch as the sleeve joint portion 540 moves downward; the elastic force of the elastic member 56 will be opposite to the pressing force of the user, so that the user needs to exert a certain additional force to overcome the elastic force of the elastic member 56 in order to continue to push the sleeve joint portion 540 and the valve core 53.

[0029] Please refer to Figure 2 The gas valve 50 further comprises a limiting boss 57 extending upward on the clamping section 21. The limiting boss 57 is sleeved outside the valve body 51, and the elastic member 56 is installed on the limiting boss 57. The limiting boss 57 extends upward and is sleeved outside the valve body 51, providing a stable installation position for the elastic member 56; the elastic member 56 is installed on the limiting boss 57, so that the elastic member 56 will not shift during operation; the limiting boss 57 is sleeved outside the valve body 51, which serves as a certain radial limiting for the valve body 51; it can prevent the valve body 51 from excessive shifting or shaking when subjected to accidental lateral force (such as force generated when the bottle is hit or shaken); this can ensure that the valve core 53 inside the valve body 51 maintains the correct positional relationship with the passage, ensuring the normal operation of the gas valve 50.

[0030] Please refer to Figure 3 and Figure 4The press-type water outlet plastic bottle further comprises a fixing shaft 60 arranged on one side of the cover segment 22 and a shaft sleeve 70 arranged on one side of the clamping segment 21 and matched with the fixing shaft 60; the shaft sleeve 70 is sleeved on the fixing shaft 60, and the cover segment 22 and the clamping segment 21 are connected by the rotating shafts of the matched fixing shaft 60 and the shaft sleeve 70. When it is needed to open or close the bottle cap 20, the fixing shaft 60 serves as the rotating center, and the shaft sleeve 70 is sleeved on the fixing shaft 60, so that the cover segment 22 can rotate relative to the clamping segment 21; when the user applies an external force to open the bottle cap 20, the cover segment 22 rotates around the fixing shaft 60; the shaft sleeve 70 stably rotates on the fixing shaft 60, ensures that the movement track of the cover segment 22 is a circular path, and can accurately control the opening and closing angle of the cover segment 22; the external force received by the bottle cap 20 can be effectively dispersed; when an external force acts on the bottle cap 20, such as the bottle is shaken during carrying, the force is transmitted and dispersed through the fixing shaft 60 and the shaft sleeve 70, the possibility that the local force is too large to cause damage to the bottle cap 20 is reduced, and thus the normal service life and sealing performance of the bottle cap 20 are ensured.

[0031] A fixed buckle 23 is arranged on the cover segment 22 away from the shaft sleeve 70, and a movable assembly 24 is arranged on the clamping segment 21 away from the fixed shaft 60 and cooperates with the fixed buckle 23. The movable assembly 24 includes a pressing member 240 extending from the side of the cover segment 22 and a movable buckle 241 in communication with the pressing member 240 and cooperating with the fixed buckle 23. A pressing channel 220 is arranged on the cover segment 22 for the pressing part 541 to move, and a limiting cavity 242 is arranged in the cover segment 22 for limiting the movement of the movable buckle 241. When the cover segment 22 rotates to close the clamping segment 21 around the shaft sleeve 70, the fixed buckle 23 on the cover segment 22 gradually approaches the movable buckle 241 on the clamping segment 21. After the fixed buckle 23 contacts the movable buckle 241, it exerts pressure on the movable buckle 241. At this time, the movable buckle 241 retreats through the pressing member 240 in communication therewith. Because the pressing member 240 has a certain elasticity or mobility, under the action of pressure, the pressing member 240 is compressed or pushed, and the movable buckle 241 moves backward, so that the fixed buckle 23 can pass smoothly. The limiting cavity 242 in the cover segment 22 plays a key role in the movement of the movable buckle 241. The shape and size of the limiting cavity 242 match those of the movable buckle 241, which limits the movement of the movable buckle 241 in a specific direction and range. For example, the limiting cavity 242 can be a groove of a specific shape, and the movable buckle 241 slides in the groove to prevent it from deviating excessively in the horizontal direction or from moving unexpectedly in the vertical direction. After the fixed buckle 23 completely passes through the movable buckle 241, the movable buckle 241 returns to the original position under the elastic restoring force or reset action of the pressing member 240, and cooperates with the fixed buckle 23 to tightly clamp the cover segment 22 and the clamping segment 21, thereby achieving the locking of the bottle cap 20. When it is necessary to open the bottle cap 20, the user presses the pressing member 240 extending from the side of the cover segment 22, so that the movable buckle 241 in communication with the pressing member 240 is displaced. The design of the pressing member 240 enables it to effectively transmit the external force applied by the user to the movable buckle 241, so that the movable buckle 241 overcomes the clamping force between the fixed buckle 23. Under the action of the pressing member 240, the movable buckle 241 moves in the limiting cavity 242 and leaves the locking position of the fixed buckle 23. Because the position of the movable buckle 241 changes, the fixed buckle 23 is no longer limited, and the cover segment 22 can rotate to open around the shaft sleeve 70. In this process, the pressing channel 220 still provides independent movement space for the pressing part 541 of the air valve 50, ensuring that even when the pressing part 541 is operated while the bottle cap 20 is being opened, it will not interfere with the opening operation of the bottle cap 20, facilitating the user to use the liquid in the bottle or perform other operations on the bottle.

[0032] Please refer to Figure 2 and Figure 4The free end of the water outlet pipe 30 on the side close to the bottle cap 20 is arranged in the opposite direction of the bottle cap 20. The free end of the water outlet pipe 30 is arranged in the opposite direction of the bottle cap 20, mainly for facilitating the liquid to flow out and guiding the liquid to flow to the target position; after the liquid in the bottle is pressed into the water outlet pipe 30 by pressing the air valve 50, the liquid flows along the water outlet pipe 30; since the direction of the free end of the water outlet pipe 30 is away from the bottle cap 20, the liquid directly flows to the container (such as a cup) below the water outlet pipe 30.

[0033] Please refer to Figure 2 and Figure 3 The bottle body 10 comprises an outer shell 11, an inner container 12 and a fixing support 13 for supporting the inner container 12, the inner container 12 is sleeved in the outer shell 11, the inner container 12 is sealingly connected with the top of the outer shell 11, and the fixing support 13 is installed on the outer shell 11, and the free end of the fixing support 13 is connected with the inner container 12. In the embodiment, the outer shell 11 is made of plastic. The fixing support 13 is a clamping groove fixed on the outer shell 11. The fixing support 13 is installed on the outer shell 11, and the free end of the fixing support 13 is connected with the inner container 12, thereby connecting the inner container 12 and the outer shell 11; the fixing support 13 tightly holds the inner container 12, thereby preventing the inner container 12 from shaking or moving in the outer shell 11; and the fixing support 13 effectively prevents the inner container 12 from being broken.

[0034] The above only expresses the preferred technical solutions of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, and the utility model also intends to include these changes and modifications.
