[0032] This application provides a press-type liquid extruder, which heats the liquid within the cavity, ensuring the extruded liquid is hot. The product can be equipped with a battery or power supply unit. When the liquid is pressed into the palm, it is warm. Furthermore, the press-type liquid extruder of this application can also be integrated into or used with other products. For example, when used with male adult products, it can heat the lubricant to a suitable temperature.

[0033] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of an embodiment of the press-type liquid extruder of this application. Figure 2 yes Figure 1 A cross-sectional view of the press-type liquid extruder in the embodiment. Figure 3 yes Figure 1 A schematic diagram of the split structure of the press-type liquid extruder in this embodiment; the press-type liquid extruder in this embodiment includes, but is not limited to, the following structures: housing 100, first valve unit 200, heating element 300, and pressing assembly 400.

[0034] Specifically, the outer shell 100 surrounds and forms a first liquid receiving cavity 101 and a second liquid receiving cavity 102, which are connected by a liquid flow channel 103.

[0035] Optionally, the outer shell 100 in this embodiment may include a first outer shell component 110, a second outer shell component 120, and a third outer shell component 130. The overall outer contour of the first outer shell component 110, the second outer shell component 120, and the third outer shell component 130 may be a cylindrical structure. The second outer shell component 120 is inserted into the first outer shell component 110. The first end of the second outer shell component 120 is used to cooperate with the first outer shell component 110 to seal and form a first liquid receiving cavity 101. The second end of the second outer shell component 120 is sealed and cooperated with the third outer shell component 130 to form a second liquid receiving cavity 102 (wherein, the first end and the second end of the second outer shell component 120 are opposite ends). The connection method between the second outer shell component 120 and the third outer shell component 130 may be a fixed connection by means of adhesive, snap-fit, etc.

[0036] Optionally, the second housing component 120 and the first housing component 110 can be detachably connected, for example, by threaded connection, snap-fit ​​connection, etc. By designing a detachable connection structure between the second housing component 120 and the first housing component 110, it is convenient to open the first liquid receiving cavity 101 and inject liquid into the first liquid receiving cavity 101.

[0037] This embodiment illustrates a structure in which the second outer shell component 120 and the first outer shell component 110 are engaged and connected. Please refer to the attached diagram. Figure 4 and Figure 5 , Figure 4 This is a structurally disassembled schematic diagram of the outer shell in an embodiment of this application. Figure 5 yes Figure 4 The partial perspective magnified view of the outer shell structure in this embodiment shows that one of the inner sidewall of the first outer shell component 110 and the outer sidewall of the second outer shell component 120 has an engaging protrusion, and the other has an engaging groove. The engaging protrusion and the engaging groove cooperate to achieve the engaging connection between the first outer shell component 110 and the first outer shell component 120. In this embodiment, the engaging groove 111 is provided on the inner sidewall of the first outer shell component 110 and the engaging protrusion 121 is provided on the outer sidewall of the second outer shell component 120 as an example. In addition, there can be multiple pairs of engaging grooves 111 and engaging protrusions 121. The illustration of this embodiment uses two pairs as an example. The specific number of engaging pairs is not specifically limited.

[0038] The engaging protrusion 121 can be a protrusion structure protruding from the outer side wall of the second housing component 120. The engaging groove 111 includes a first groove segment 1111 and a second groove segment 1112. The extending direction of the first groove segment 1111 is approximately parallel (or substantially parallel) to the axial direction of the first housing component 110 (that is, the direction in which the second housing component 120 is inserted into the first housing component 110). The second groove segment 1112 extends circumferentially along the first housing component 110.

[0039] Optionally, a limiting protrusion 113 is provided at the end of the second groove segment 1112 away from the first groove segment 111. The distance between the limiting protrusion 113 and the end of the second groove segment 1112 (the end away from the first groove segment 111) is slightly larger than the size of the engaging protrusion 121 (this position is used to accommodate the fully engaged state of the engaging protrusion 121). The width of the second groove segment 1112 at the location of the limiting protrusion 113 is reduced, that is, the width of the second groove segment 1112 at the location of the limiting protrusion 113 is smaller than the width at other locations of the second groove segment 1112. A limiting accommodating area 11120 is formed between the limiting protrusion 113 and the end of the second groove segment 1112. The limiting accommodating area 11120 is used to accommodate the engaging protrusion 121, thereby limiting the loosening and sliding of the engaging protrusion 121 and preventing the engaging protrusion 121 from sliding back out of the second groove segment 1112.

[0040] The assembly method of the second outer shell component 120 and the first outer shell component 110 is as follows: First, align the engaging protrusion 121 with the end of the first groove segment 1111. Then, insert the second outer shell component 120 into the first outer shell component 110. At this time, the engaging protrusion 121 slides along the first groove segment 1111. When it slides to the bottom of the first groove segment 1111 (that is, the connection between the first groove segment 1111 and the second groove segment 1112), the second outer shell component 120 rotates circumferentially relative to the first outer shell component 110. During this process, the engaging protrusion 121 slides and passes along the second groove segment 1112, limiting the protrusion 113, until the engaging protrusion 121 slides to... Figure 5 The position shown indicates that the card is engaged. The unlocking process is the reverse of the sliding process.

[0041] The first end of the second outer shell component 120 is provided with a guide tube 140. The guide tube 140 can be an integral structure with the second outer shell component 120. The guide tube 140 forms a liquid flow channel 103. One end of the guide tube 140 is connected to the first liquid receiving cavity 101, and the other end is inserted into the bottom of the second liquid receiving cavity 102.

[0042] Optionally, in this embodiment, the volume of the second liquid-containing cavity 102 is smaller than the volume of the first liquid-containing cavity 101. The first liquid-containing cavity 101 stores a large amount of liquid, while the second liquid-containing cavity 102, serving as a heating cavity, only needs to store a small amount of liquid. This different liquid storage capacity design between the second liquid-containing cavity 102 and the first liquid-containing cavity 101 allows for control of the liquid heating time (reducing heating time) and improving the user experience.

[0043] Please refer to the following: Figure 6 , Figure 6 This is a partial structural schematic diagram of an embodiment of the press-type liquid extruder of this application. In this embodiment, the first valve unit 200 is provided corresponding to the liquid flow channel 103 and is used to block and open the liquid flow channel 103. When the first valve unit 200 opens the liquid flow channel 103, the liquid in the first liquid receiving cavity 101 can flow into the second liquid receiving cavity 102 through the liquid flow channel 103.

[0044] Optionally, the first valve unit 200 in this embodiment includes a first connector 210, a first spring 220, and a first sealing member 230. The first connector 210 is fixedly connected to the boss 122 inside the second housing detachment 120, specifically by snap-fit. The first connector 210 has a liquid passage hole 211 in the middle for liquid to flow through.

[0045] One end of the first spring 220 abuts against the first connector 210, and the other end abuts against the first sealing member 230. In the absence of external force (no pressure difference between the first liquid receiving cavity 101 and the second liquid receiving cavity 102), the first spring 220 abuts against the first sealing member 230, causing the first sealing member 230 to block the liquid flow channel 103 (the funnel-shaped structure at the end), preventing liquid from flowing back from the second liquid receiving cavity 102 into the first liquid receiving cavity 101. The first sealing member 230 can be a small ball or a plug structure; no specific limitation is made here.

[0046] Please continue reading. Figure 2 and Figure 6 A heating element 300 is disposed within the second liquid receiving cavity 102 for heating the liquid within the cavity. The heating element 300 can be any one or a combination of several of the following: a heating coil, an ultrasonic heater, a resistance heating film, and a resistance heating element. In this embodiment, it can be a metal sheet structure, with the metal sheet integrally injection molded with the outer shell (second outer shell component 120). This design offers advantages such as structural stability and prevention of leakage.

[0047] The metal sheet has two parts: the first part is the connecting part 310, which is embedded in the second outer shell detachment 120 and integrally injection molded with the second outer shell detachment 120; the second part is the heating part 320, which extends into the second liquid receiving cavity 102 to heat the liquid in the second liquid receiving cavity 102.

[0048] Alternatively, please continue reading Figure 2 and Figure 3 One end of the pressing component 400 is located inside the second liquid receiving cavity 102, and the other end protrudes from the outer shell 100. When the pressing component 400 is pressed, the liquid in the second liquid receiving cavity 102 can be ejected through the through hole 411 on the pressing component 400.

[0049] In this embodiment, the pressing component 400 includes a button cap 410 and a sealing plug 420. The sealing plug 420 is disposed within the second liquid receiving cavity 102. Under external pressing pressure, the button cap 410 can push the sealing plug 420 to move, thereby compressing the volume of the second liquid receiving cavity 102, so that the liquid in the second liquid receiving cavity 102 is ejected through the through hole 411 on the button cap 410. To improve sealing, a first sealing rubber ring 421 can also be provided between the sealing plug 420 and the side wall of the second outer casing detachable part 120.

[0050] Optionally, the third housing assembly 130 is provided with a liquid outlet channel 131 in the middle. The press-type liquid extruder also includes a second valve unit 500, which is provided corresponding to the liquid outlet channel 131 and is used to block and open the liquid outlet channel 131. When the second valve unit 500 opens the liquid outlet channel 131, the liquid in the second liquid receiving cavity 102 can flow through the liquid outlet channel 131 and be sprayed out through the through hole 411 on the button cap 410.

[0051] Optionally, the second valve unit 500 in this embodiment includes a second connector 510, a second spring 520, and a second sealing member 530. One end of the second connector 510 is fixedly connected to the button cap 410, and the other end is inserted into the liquid outlet channel 131 and can slide along the liquid outlet channel 131. A second sealing rubber ring 512 may be provided on the outer periphery of the second connector 510. The second connector 510 is provided with a connecting flow channel 511. The two ends of the connecting flow channel 511 are respectively connected to the through hole 411 of the button cap 410 and the liquid outlet channel 131 of the third housing detachment 130. One end of the second spring 520 supports the second connector 510, and the other end supports the second sealing member 530.

[0052] In the absence of external force (there is no pressure difference between the second liquid receiving cavity 102 and the liquid outlet channel 131), the second spring 520 holds the second sealing member 530, so that the second sealing member 530 blocks the liquid outlet channel 131 (the funnel-shaped structure at the end position). The second sealing member 530 can also be a small ball or a plug structure, which is not specifically limited here.

[0053] Alternatively, please continue reading Figure 2 and Figure 3 In this embodiment, the pressing component 400 also includes a reset spring 430. The two ends of the reset spring 430 respectively hold the button cap 410 and the third housing component, and are used to reset the button cap 410.

[0054] The working principle and process of the press-type liquid extruder in this embodiment are as follows: First, liquid is injected into the first liquid receiving cavity 101. Pressing the button cap 410 pushes the sealing plug 420 to slide along the second liquid receiving cavity 102. During the reset process of the button cap 410 and the sealing plug 420, a negative pressure is formed in the second liquid receiving cavity 102. Then, the first sealing member 230 of the first valve unit 200 opens the liquid flow channel 103, and the liquid flows into the second liquid receiving cavity 102 through the liquid flow channel 103. The heating member 300 heats the liquid flowing into the second liquid receiving cavity 102. When the user presses the button again... When the cap 410 is activated, the second sealing member 530 of the second valve unit 500 is driven to open the liquid outlet channel 131 under the action of negative pressure. The heated liquid is sprayed out through the liquid outlet channel 131, the connecting flow channel 511 and the through hole 411 of the button cap 410 in sequence. During the reset process of the button cap 410 and the sealing plug 420, negative pressure is formed again in the second liquid receiving cavity 102. The first sealing member 230 of the first valve unit 200 opens the liquid flow channel 103. The liquid flows into the second liquid receiving cavity 102 through the liquid flow channel 103 and circulates in sequence, so that the liquid continuously enters the second liquid receiving cavity 102 and is heated and sprayed out.

[0055] Alternatively, please continue reading Figures 1 to 3 The press-type liquid extruder in this embodiment also includes a power supply unit 600, which is connected to the first housing assembly 110 and electrically connected to the heating element 300. The power supply unit 600 can be a battery or other structural form.

[0056] Optionally, in this embodiment, the power supply unit 600 is detachably connected to the first housing assembly 110. Please refer to the following: Figure 3 , Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of a press-type liquid extruder according to an embodiment of the present application, showing the removal of the power supply unit. Figure 8This is a schematic diagram of the installation structure of the power supply unit and the housing in an embodiment of the press-type liquid extruder of this application. In this embodiment, the outer wall of the housing (specifically, the first housing component 110) is provided with a mounting groove 112, and the power supply unit 600 is snapped into the mounting groove 112.

[0057] The mounting groove 112 extends in the opposite direction to the axis of the first housing assembly 110 and penetrates the end face of the first housing assembly 110. The power supply unit 600 extends along... Figure 8 The power supply unit 600 is installed and secured in the mounting slot 112 in the direction of the middle arrow, with the power supply unit 600 fully secured in the mounting slot 112. Figure 1 In the middle state), the outer side of the power supply unit 600 is coplanar with the outer side wall of the housing or has a slight step difference, that is, the power supply unit 600 is just embedded in the mounting groove 112 of the housing, so that the overall appearance of the press-type liquid extruder is consistent.

[0058] Alternatively, please continue reading Figure 2 , Figure 3 as well as Figure 6 In this embodiment, the power supply unit 600 may include a housing 610, a battery cell 620, and a control circuit board 630. The battery cell 620 and the control circuit board 630 are disposed inside the housing 610. The housing 610 has exposed connection terminals 640. One end of the connection terminal 640 is connected to the control circuit board 630, and the other end is connected to the heating element 300. Specifically, it can be directly connected to the exposed part of the connection portion 310 of the heating element 300, or it can be connected via a probe. The connection terminal 640 can be a pogo pin structure. The detailed structure of the connection terminal 640 is within the understanding of those skilled in the art and will not be described in detail here.

[0059] Optionally, please refer to the following as well. Figure 2 and Figure 9 , Figure 9 This is a partial structural diagram of another embodiment of the press-type liquid extruder of this application. In this embodiment, the bottom of the mounting groove 112 on the first outer shell detachable part 110 is provided with a liquid injection through hole 1120. The liquid injection through hole 1120 communicates with the first liquid receiving cavity. The liquid injection through hole can be sealed by a rubber stopper 115. The user can inject liquid into the first liquid receiving cavity through the liquid injection through hole 1120. The liquid injection through hole 1120 does not affect the appearance. In addition, an injection-type rubber stopper can be used for sealing (the rubber stopper 115 can be detachable or non-detachable), which has excellent waterproof performance.

[0060] The press-type liquid extruder provided in this application embodiment has two liquid receiving cavities. A heating element is installed in one of the liquid receiving cavities. The heating element can be used to heat the liquid before it is ejected, so that the temperature of the ejected liquid is suitable and the user comfort is improved.
