Specific implementation

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] Please refer to Figures 1-8 The utility model provides a technical scheme:

[0029] A press bottle that prevents liquid leakage mainly comprises a bottle body 1, a press pump head 2 and a plurality of auxiliary components. The installation part 201 of the press pump head 2 is installed on the bottle body 1 in a threaded connection mode. This connection mode is firm and reliable, and can ensure that the press pump head 2 will not easily fall off the bottle body 1 during use. At the same time, the sealing performance of the thread is good, which can effectively prevent the liquid in the bottle from leaking.

[0030] The connection between the installation part 201 and the bottle body 1 is usually provided with a sealing gasket, which further enhances the sealing performance and prevents the liquid from seeping out of the connection.

[0031] The installation part 201 and the press head 202 are connected through a pump suction assembly. The pump suction assembly generally comprises a spring, a piston, a liquid inlet valve and a liquid outlet valve and the like. One end of the spring is fixed on the installation part 201, and the other end is connected with the piston. The piston can move up and down in the pump body under the action of the spring.

[0032] The liquid inlet valve is located at the bottom of the pump body and is connected to the inside of the bottle body 1 through a suction pipe. The liquid outlet valve is located inside the pressing head 202 and is connected to the liquid outlet pipe 3. When the piston moves downward, the liquid inlet valve opens and the liquid outlet valve closes, and the liquid in the bottle is sucked into the pump body; when the piston moves upward, the liquid inlet valve closes and the liquid outlet valve opens, and the liquid in the pump body is pressed out of the liquid outlet pipe 3.

[0033] The outlet of the pressing head 202 is fixedly connected with a liquid outlet pipe 3 made of elastic material. This connection can be achieved in a sleeved manner, with the liquid outlet pipe 3 being tightly sleeved on the outlet of the pressing head 202, and then being fixed by means of glue or hot melting, to ensure firm connection and good sealing.

[0034] The elastic material of the liquid outlet pipe 3 can be rubber, silicone or the like, and has good flexibility and sealing performance. When subjected to external pressure, the liquid outlet pipe 3 can deform, thereby realizing opening and closing of the pipe.

[0035] The safety cover 4 is slidably arranged on the pressing head 202 and coaxial with the pressing head 202. The inner diameter of the safety cover 4 is slightly larger than the outer diameter of the pressing head 202, so that the safety cover 4 can smoothly slide on the pressing head 202.

[0036] The safety cover 4 is provided with a through hole at the position of the liquid outlet pipe 3. The size and shape of the through hole are slightly larger than the cross section of the liquid outlet pipe 3, so that the liquid can flow out of the liquid outlet pipe 3 under certain conditions.

[0037] A reset component and a limiting component are arranged between the pressing head 202 and the safety cover 4. The reset component is a reset spring 5 fixedly arranged between the pressing head 202 and the safety cover 4. One end of the reset spring 5 can be fixed on the pressing head 202 by means of a hook, and the other end can be fixed on the safety cover 4 by means of the same hook. When the safety cover 4 is subjected to external force, the reset spring 5 can provide a restoring force to make the safety cover 4 return to the initial position.

[0038] The safety cover 4 is provided with a pressing flange 401 at the position of the through hole. The shape and size of the pressing flange 401 are adapted to the liquid outlet pipe 3, and the pressing flange 401 can tightly press the liquid outlet pipe 3 when the safety cover 4 is in the initial state, so that the liquid outlet pipe 3 is in a closed state. The material of the pressing flange 401 can be the same as that of the safety cover 4.

[0039] As Figure 1 and 2As shown, when the press bottle is not in use, the reset spring 5 is in a natural state of extension, the reset spring 5 presses the safety cover 4, the safety cover 4 is far away from the top surface of the pressing head 202, at this time, the through hole on the safety cover 4 is relatively misaligned with the liquid outlet pipe 3, the extrusion flange 401 at the position of the through hole will tightly extrude the elastic liquid outlet pipe 3. Since the liquid outlet pipe 3 is elastic, it will deform when extruded, thereby being in a closed state. In this way, the liquid in the bottle can be prevented from flowing out of the liquid outlet pipe 3 due to its own flow, ensuring that there is no leakage when not in use.

[0040] As shown in Figure 3 and 4 When the user is ready to squeeze out the lotion, the safety cover 4 will be pressed down first. In this process, the external force applied by the user overcomes the elastic force of the reset spring 5, so that the reset spring is compressed. With the downward movement of the safety cover 4, the extrusion flange 401 at the position of the through hole gradually moves away from the liquid outlet pipe 3 and no longer extrudes it. At this time, the elastic liquid outlet pipe 3 loses the pressure of the extrusion flange 401 and will rebound under the action of its own elasticity to restore its original state, thereby being in a connected state.

[0041] As shown in Figure 6 and 7 The user continues to press the safety cover 4, which will cause the pressing head 202 to descend. When the pressing head 202 descends, the lotion is pumped out by the pumping assembly. Specifically, when the pressing head 202 descends, it drives the piston to move downward in the pump body, at this time the liquid inlet valve is opened and the liquid outlet valve is closed, and the liquid in the bottle is sucked into the pump body. With the continued descent of the pressing head 202, the piston exerts pressure on the liquid in the pump body, and when the pressure reaches a certain level, the liquid outlet valve is opened and the liquid inlet valve is closed, and the liquid in the pump body is pressed out of the liquid outlet pipe 3.

[0042] After the extrusion is completed, the user releases his hand, at this time the spring in the pumping assembly loses the action of external force and begins to restore its original state, driving the pressing head 202 to rebound. As shown in Figure 1 and 2 At the same time, the reset spring 5 also drives the safety cover 4 to rebound under the action of its own elasticity. With the upward movement of the safety cover 4, the extrusion flange 401 at the position of the through hole again extrudes the liquid outlet pipe 3, causing the liquid outlet pipe 3 to be in a closed state. In this way, the extrusion process of the lotion is completed, and after use it can automatically restore to the initial state of preventing leakage.

[0043] Example Two:

[0044] In the press bottle, as shown in Figure 5As shown, the limiting assembly includes several first limiting blocks 6 fixedly disposed on the side wall of the pressing head 202. These first limiting blocks 6 are connected to the pressing head 202 by integral molding. Several equal number of second limiting blocks 7 are disposed on the inner wall of the safety cover 4. The second limiting blocks 7 can also be integrally molded with the safety cover 4 or fixed to the inner wall of the safety cover 4 by other reliable connection methods.

[0045] When the safety cover 4 slides on the pressing head 202, the first limiting block 6 and the second limiting block 7 work together. Specifically, during normal use, the sliding range of the safety cover 4 is limited by the first limiting block 6 and the second limiting block 7. When the safety cover 4 slides down to a certain position, the second limiting block 7 will contact the first limiting block 6, preventing the safety cover 4 from moving further downward, thereby preventing the safety cover 4 from falling off the pressing head 202. This limiting function ensures the stability and reliability of the safety cover 4 during use.

[0046] Both the first limiting block 6 and the second limiting block 7 are provided with wedge surfaces, and the wedge surfaces of the first limiting block 6 and the second limiting block 7 are arranged oppositely. This design has a significant advantage for the machining personnel during assembly. During the assembly process, due to the presence of the wedge surfaces, when the safety cover 4 is placed on the pressing head 202, the wedge surfaces of the first limiting block 6 and the second limiting block 7 will guide each other, making the assembly smoother. The machining personnel only need to gently slide the safety cover 4 downwards, and the guiding effect of the wedge surfaces will cause the first limiting block 6 and the second limiting block 7 to automatically align, thus completing the assembly work conveniently and quickly.

[0047] like Figure 5 As shown, the press head 202 has a threaded hole, and one end of the liquid outlet pipe 3 is fixedly connected to the threaded tube 12. The liquid outlet pipe 3 and the threaded tube 12 can be fixed together by integral molding or a reliable connection method. During assembly, the operator screws the threaded tube 12 on the liquid outlet pipe 3 into the threaded hole on the press head 202, thereby achieving a fixed connection between the liquid outlet pipe 3 and the press head 202.

[0048] Example 3:

[0049] On the basis of the above-mentioned embodiments, as shown in FIG. 7, the limiting assembly further comprises a first limiting ring 10 fixedly arranged on the pressing head 202. The first limiting ring 10 is fixed by means of one-piece forming. Meanwhile, a second limiting ring 11 is also fixedly arranged on the safety cover 4. The second limiting ring 11 can also be fixed by means of one-piece forming with the safety cover 4. When the user uses the squeeze bottle, the safety cover 4 will slide on the pressing head 202 with the pressing of the safety cover 4. In this process, when the safety cover 4 slides to a certain position, the first limiting ring 10 and the second limiting ring 11 will contact each other, thereby preventing the safety cover 4 from continuing to move downward. Such a setting can effectively prevent the user from overstraining during the squeezing process, avoiding damage to the return spring 5 due to excessive squeezing beyond its elastic limit.

[0050] Secondly, the limiting assembly further comprises a plurality of guide strips 8 fixedly arranged on the side wall of the pressing head 202. The guide strips 8 can be fixed on the side wall of the pressing head 202 by means of one-piece forming with the pressing head 202. Correspondingly, a plurality of guide grooves 9 are fixedly arranged on the inner wall of the safety cover 4. The guide strips 8 and the guide grooves 9 are used in cooperation and equal in number, and the guide strips 8 are slidingly arranged in the guide grooves 9. When the safety cover 4 slides on the pressing head 202, the cooperation of the guide strips 8 and the guide grooves 9 can ensure that the sliding direction of the safety cover 4 always remains stable.

[0051] In addition, a detachable bottle cap 13 is arranged on the bottle body 1. The bottle cap 13 can be installed on the bottle body 1 by means of threaded connection. An outer thread is arranged at the opening of the bottle body 1, and an inner thread matching the outer thread is arranged on the inner wall of the bottle cap 13. When the bottle cap 13 is screwed on the bottle body 1, it can tightly close the bottle opening, preventing dust, impurities, etc. from entering the bottle, and also providing additional protection when the squeeze bottle is not in use. When it is necessary to use the squeeze bottle or to perform cleaning or other operations on the bottle, the bottle cap 13 can be conveniently unscrewed.

[0052] Working principle: the utility model is in the process of using, not use, reset spring 5 is in natural stretch state, open the safety cover 4, make extrusion flange 401 of safety cover 4 extrude elastic liquid outlet pipe 3, and liquid outlet pipe 3 is closed to prevent leakage. When the user prepares to use, first press down the safety cover 4, overcomes the elastic force of reset spring 5 and makes spring compression, extrusion flange 401 is away from liquid outlet pipe 3 at this moment, and liquid outlet pipe 3 is resilient under the self elastic action and is connected state. Then continue to press the safety cover 4, and the safety cover 4 drives the pressing head 202 to descend, and the piston movement of pump suction assembly is first opened liquid inlet valve and absorbs the liquid in the bottle, and then closes the liquid inlet valve and opens the liquid outlet valve and extrudes the liquid from liquid outlet pipe 3. After extrusion, the user releases the hand, and the spring of pump suction assembly and reset spring 5 drive pressing head 202 and safety cover 4 respectively and rebound, and extrusion flange 401 extrudes liquid outlet pipe 3 again to make it closed, and restore to the initial state of preventing liquid leakage. Although the embodiment of the utility model has been shown and described, it can be understood by those skilled in the art that the embodiment can be changed, modified, replaced and modified in various ways without departing from the principle and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
