[0002] With the improvement of life quality, people's demand for massage experience is increasingly strict. Although the traditional electric hammer massage equipment has certain application in the past, its defects are increasingly obvious. From the physical characteristics, the existing massage equipment device is bulky and heavy, which not only makes it very inconvenient to carry and store, but also brings a great burden to the user in actual operation. In terms of energy consumption, the traditional electric hammer massage has high energy consumption and relies on high-voltage power supply, which undoubtedly brings many safety hazards, such as increased risk of electric shock. What is particularly prominent is that it cannot be adapted to small battery power supply, which greatly limits the use scene and is difficult to meet the instant massage demand of people in the current outdoor leisure, mobile office and other diversified scenes.

[0003] Looking at the core component of the massage equipment: the pump, the existing pump structure has obvious defects when realizing the in-out function of the fluid (especially gas, which plays a key role in creating impact massage effect). For example, the current fluid bag deflation mode mostly relies on simple deflation valve natural deflation. This mode has poor flexibility, which leads to low switching efficiency of the fluid between the pump chamber and the fluid bag, directly affecting the rhythm and uniformity of the massage, resulting in unsatisfactory overall massage effect, which is difficult to meet the growing fine experience demand of users.

DETAILED DESCRIPTION

[0034] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined invention purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments. Embodiment one

[0035] As shown in the figure, an impact massage pump comprises a pump cavity 1, a fluid bag 2 and a driving device. Figure 1 The pump cavity 1 contains fluid, which can be liquid or gas. In this embodiment, the fluid is gas. The pump cavity 1 has a channel 12 for the fluid to enter or exit, through which the fluid bag 2 and the pump cavity 1 are in communication.

[0036] The channel 12 connects the pump cavity 1 and the fluid bag 2, and the unique channel structure enables the fluid to switch quickly and efficiently between the pump cavity 1 and the fluid bag 2. This high-speed switching mechanism enhances the impact of the massage, allowing users to more intuitively feel the massage effect and significantly improving the user's sense of immersion.

[0037] In this embodiment, the fluid bag 2 has massage protrusions 21 on the outer side wall. The fluid bag is designed with a flat concept, which effectively reduces the overall weight of the device compared to traditional designs. At the same time, the massage protrusions are arranged on the surface of the fluid bag, and under the action of fluid pressure, these massage protrusions can accurately act on the human body acupoints, enhancing the massage stimulation effect, deeply relieving muscle fatigue and achieving efficient massage.

[0038] The driving device comprises a pushing part movably connected in the pump cavity and a power part driving the pushing part. The pushing part moves back and forth in the pump cavity under the driving of the power part, so that the fluid flows back and forth between the pump cavity and the fluid bag.

[0039] The pushing part is a piston or a diaphragm. In this embodiment, the pushing part is a diaphragm 11.

[0040] In this embodiment, the power part is a low-voltage direct-current brush motor, and the power part is in transmission connection with the pushing part through an eccentric wheel 3 and a connecting rod 31.

[0041] The power part can be directly connected to the pushing part through the eccentric wheel alone. This is more suitable for the case where the power part only drives one pump cavity. When the power part needs to drive multiple pump cavities, such as

[0042] Figure 3 ​As shown, the eccentric wheel 3 is driven by a low-voltage DC brush motor (not shown in the figure), the eccentric wheel is connected to two connecting rods 31, and the two connecting rods are respectively connected to the diaphragms 11 in the two pump cavities. Among them, the pump cavity with a switching mechanism (the upper pump cavity in the figure) is an inflation massage pump, and the pump cavity without a switching mechanism (the lower pump cavity in the figure) is an impact massage pump, so as to realize the use state that a low-voltage DC brush motor drives an impact massage pump and an inflation massage pump at the same time.

[0043] The output end of the low-voltage DC brush motor is configured with a speed reduction mechanism.

[0044] A low-voltage DC brush motor is selected as the core driving force source. The motor has significant economic advantages, can effectively reduce the user's use cost while reducing the manufacturing cost of the equipment, and runs in a low-voltage environment, fundamentally avoiding the safety risks brought by high voltage and protecting the personal safety of the user. Moreover, the motor has low power consumption and excellent power saving characteristics, and is designed to be externally connected to a battery, so that it can perfectly adapt to outdoor and mobile use scenarios, greatly expanding the application range of the equipment.

[0045] The speed reduction mechanism is provided to accurately control the power output by the motor. On the one hand, it ensures that there is enough power to drive the massage action, so that the massage force is strong and stable; on the other hand, through reasonable speed reduction ratio setting, it effectively avoids user discomfort caused by excessively high power output frequency, ensures that the massage frequency is in line with human physiological feelings, and optimizes the user experience.

[0046] In this embodiment, the pump cavity 1 has a fluid supplement port 13. When the pore diameter of the fluid supplement port is less than 0.5 mm, a first one-way valve can not be configured due to the small pore diameter, and at this time the fluid supplement port has a pressure relief function.

[0047] When the pore diameter of the fluid supplement port is greater than or equal to 0.5 mm, the fluid supplement port 13 is connected with a first one-way valve 14 for preventing fluid from flowing out of the pump cavity, and the opening pressure of the first one-way valve 14 is greater than 2 Kpa.

[0048] The fluid supplement port can monitor and supplement fluid in real time, effectively prevent massage failure caused by negative pressure, and ensure the continuity and stability of the massage process.

[0049] The opening pressure threshold of the first one-way valve 14 is set, and the first one-way valve 14 needs to be opened under the condition of negative pressure greater than 2 Kpa. In this way, the flow and pressure of the fluid entering the fluid bag can be accurately controlled, the over-expansion of the fluid bag due to excessive inflow of fluid can be effectively prevented, the damage of the equipment can be avoided, the service life of the equipment can be prolonged, and the use safety can be ensured.

[0050] In order to realize multiple massage modes, such as Figure 2As shown, the channel 12 is provided with a switching mechanism, which includes a second one-way valve 41 and a driving unit, the second one-way valve 41 reciprocates between the channel 12 and away from the channel 12 under the driving of the driving unit, and the second one-way valve is used to prevent the fluid from flowing out of the fluid bag when it is located at the channel 12. In this embodiment, the driving unit adopts a second electromagnetic valve 4.

[0051] The second one-way valve is precisely controlled by the second electromagnetic valve under the electric control. When the second one-way valve fails (i.e. the second electromagnetic valve is away from the channel), the massage impact pump switches to the impact pump mode (the fluid can flow freely between the pump cavity and the fluid bag), which can output strong impact massage force; when the second one-way valve works normally (i.e. the second one-way valve is located at the channel), the massage impact pump operates as a conventional pump (the fluid can only continuously flow into the fluid bag), the fluid bag continuously expands under the condition of not breaking the explosion limit, providing a relatively soft massage effect, realizing one pump with two uses, and flexibly adapting to different massage needs.

[0052] The above-mentioned switching mechanism is a preferred case adopted in this embodiment. When the number of fluid bags is multiple, as shown in Figure 4 each fluid bag is provided with a first electromagnetic valve 15 at the connection with the channel to control the opening and closing of the connection, and the use of which fluid bag is selected by controlling the opening and closing of the first electromagnetic valve.

[0053] When the channel is not provided with a switching mechanism, and the number of fluid bags is multiple, each fluid bag is provided with a first electromagnetic valve 15 at the connection with the channel to control the opening and closing of the connection, but the inlet of part of the fluid bags is provided with a pressure maintaining valve 5, and only the fluid bag with the first electromagnetic valve, the structure of which is as shown in Figure 5 , which is the structure of the impact massage pump; the fluid bag with the pressure maintaining valve 5, the structure of which is as shown in Figure 6 , which is the structure of the inflation massage pump. The pressure maintaining valve 5 and the first electromagnetic valve 15 at this position jointly constitute a pressure maintaining electromagnetic valve, which functions as a one-way valve when energized (the connection between the first electromagnetic valve and the channel has a fluid discharge port 16, and the fluid in the fluid bag can be discharged from the fluid discharge port when the first electromagnetic valve is closed), and the pump cavity can only continuously provide fluid to the fluid bag in one direction, and the fluid bag continuously expands under the condition of not breaking the explosion limit, providing a relatively soft massage effect; when de-energized, the pressure maintaining electromagnetic valve is closed, and switches to the impact pump mode (the fluid can flow freely between the pump cavity and the fluid bag), which can output strong impact massage force. That is, the pump structure with the pressure maintaining electromagnetic valve has the function of one pump with two uses, and can be switched between the impact massage pump and the inflation massage pump.

[0054] A multi-path control system is introduced to realize flexible switching of multi-point massage modes in an economical and efficient manner. Users can customize personalized massage programs for different body parts by simple operation, such as setting different massage modes for shoulder, waist, leg, etc., to meet diversified massage needs.

[0055] The use method of the device is as follows:

[0056] 1. Start preparation: turn on the power of the device, start the low-voltage DC brush motor, and the power output by the motor is first adjusted by the reduction mechanism to ensure that the power output meets the initial massage requirements.

[0057] 2. Power transmission: the power after reduction drives the eccentric wheel to rotate, the eccentric wheel drives the connecting rod connected thereto to move, and the connecting rod promotes the diaphragm to make reciprocating motion in the pump cavity according to the predetermined track to provide power basis for fluid flow.

[0058] 3. Fluid circulation: with the reciprocating motion of the diaphragm, the fluid in the pump cavity flows quickly to the fluid bag or returns from the fluid bag to the pump cavity under the action of the pressure difference, realizing efficient switching of the fluid between the two areas and creating a rhythmic massage impact effect.

[0059] 4. Intelligent regulation: users can change the massage frequency of the fluid bag by adjusting the power of the motor according to their own needs. For example, when relaxation is needed, reduce the motor power to achieve low-frequency gentle massage; when deep muscle stimulation is needed, increase the motor power to achieve high-frequency strong massage, meeting the individualized massage rhythm needs.
